+# SmartData Project Overview
+
+This document provides a high-level overview of the SmartData library (`@push.rocks/smartdata`), its architecture, core components, and key features—including recent enhancements to the search API.
+
+## 1. Project Purpose
+- A TypeScript‑first wrapper around MongoDB that supplies:
+  - Strongly‑typed document & collection classes
+  - Decorator‑based schema definition (no external schema files)
+  - Advanced search capabilities with Lucene‑style queries
+  - Built‑in support for real‑time data sync, distributed coordination, and key‑value EasyStore
+
+## 2. Core Concepts & Components
+- **SmartDataDb**: Manages the MongoDB connection, pooling, and initialization of collections.
+- **SmartDataDbDoc**: Base class for all document models; provides CRUD, upsert, and cursor APIs.
+- **Decorators**:
+  - `@Collection`: Associates a class with a MongoDB collection
+  - `@svDb()`: Marks a field as persisted to the DB
+  - `@unI()`: Marks a field as a unique index
+  - `@index()`: Adds a regular index
+  - `@searchable()`: Marks a field for inclusion in text searches or regex queries
+- **SmartdataCollection**: Wraps a MongoDB collection; auto‑creates indexes based on decorators.
+- **Lucene Adapter**: Parses a Lucene query string into an AST and transforms it to a MongoDB filter object.
+- **EasyStore**: A simple, schema‑less key‑value store built on top of MongoDB for sharing ephemeral data.
+- **Distributed Coordinator**: Leader election and task‑distribution API for building resilient, multi‑instance systems.
+- **Watcher**: Listens to change streams for real‑time updates and integrates with RxJS.
+
+## 3. Search API
+SmartData provides a unified `.search(query[, opts])` method on all models with `@searchable()` fields:
+
+- **Supported Syntax**:
+  1. Exact field:value (e.g. `field:Value`)
+  2. Quoted phrases (e.g. `"exact phrase"` or `'exact phrase'`)
+  3. Wildcards: `*` (zero or more chars) and `?` (single char)
+  4. Boolean operators: `AND`, `OR`, `NOT`
+  5. Grouping: parenthesis `(A OR B) AND C`
+  6. Range queries: `[num TO num]`, `{num TO num}`
+  7. Multi‑term unquoted: terms AND’d across all searchable fields
+  8. Empty query returns all documents
+
+- **Fallback Mechanisms**:
+  1. Text index based `$text` search (if supported)
+  2. Field‑scoped and multi‑field regex queries
+  3. In‑memory filtering for complex or unsupported cases
+
+### New Security & Extensibility Hooks
+The `.search(query, opts?)` signature now accepts a `SearchOptions<T>` object:
+```ts
+interface SearchOptions<T> {
+  filter?: Record<string, any>;        // Additional MongoDB filter AND‑merged
+  validate?: (doc: T) => boolean;      // Post‑fetch hook to drop results
+}
+```
+- **filter**: Enforces mandatory constraints (e.g. multi‑tenant isolation) directly in the Mongo query.
+- **validate**: An async function that runs after fetching; return `false` to exclude a document.
+
+## 4. Testing Strategy
+- Unit tests in `test/test.search.ts` cover basic search functionality and new options:
+  - Exact, wildcard, phrase, boolean and grouping cases
+  - Implicit AND and mixed free‑term + field searches
+  - Edge cases (non‑searchable fields, quoted wildcards, no matches)
+  - `filter` and `validate` tests ensure security hooks work as intended
+- Advanced search scenarios are covered in `test/test.search.advanced.ts`.
+
+## 5. Usage Example
+```ts
+// Basic search
+const prods = await Product.search('wireless earbuds');
+
+// Scoped search (only your organization’s items)
+const myItems = await Product.search('book', { filter: { ownerId } });
+
+// Post‑search validation (only cheap items)
+const cheapItems = await Product.search('', { validate: p => p.price < 50 });
+```

-### Setting Up and Connecting to the Database
+## 🎯 Quick Start
 
-Before interacting with the database, you need to set up and establish a connection. The `SmartdataDb` class handles connection pooling and automatic reconnection.
+### 1️⃣ Connect to Your Database
 
 ```typescript
 import { SmartdataDb } from '@push.rocks/smartdata';
 
-// Create a new instance of SmartdataDb with MongoDB connection details
+// Create a database instance with smart defaults
 const db = new SmartdataDb({
-  mongoDbUrl: 'mongodb://<USERNAME>:<PASSWORD>@localhost:27017/<DBNAME>',
+  mongoDbUrl: 'mongodb://localhost:27017/myapp',
-  mongoDbName: 'your-database-name',
+  mongoDbName: 'myapp',
-  mongoDbUser: 'your-username',
+  mongoDbUser: 'username',
-  mongoDbPass: 'your-password',
+  mongoDbPass: 'password',
+  
+  // Optional: Configure connection pooling (new!)
+  maxPoolSize: 100,          // Max connections in pool (default: 100)
+  maxIdleTimeMS: 300000,     // Max idle time (default: 5 minutes)
+  serverSelectionTimeoutMS: 30000  // Connection timeout (default: 30s)
 });
 
-// Initialize and connect to the database
+// Initialize with automatic retry and connection pooling
-// This sets up a connection pool with max 100 connections
 await db.init();
 ```
 
-### Defining Data Models
+### 2️⃣ Define Your Data Models
-
-Data models in `@push.rocks/smartdata` are classes that represent collections and documents in your MongoDB database. Use decorators such as `@Collection`, `@unI`, and `@svDb` to define your data models.

-### CRUD Operations
+### 3️⃣ Perform CRUD Operations
-
-`@push.rocks/smartdata` simplifies CRUD operations with intuitive methods on model instances.
-
-#### Create
 
 ```typescript
-const newUser = new User('myUsername', 'myEmail@example.com');
+// ✨ Create
-await newUser.save(); // Save the new user to the database
+const user = new User('johndoe', 'john@example.com');
+await user.save();
+
+// 🔍 Read
+const foundUser = await User.getInstance({ username: 'johndoe' });
+const allUsers = await User.getInstances({ email: 'john@example.com' });
+
+// ✏️ Update
+foundUser.email = 'newemail@example.com';
+await foundUser.save();
+
+// 🔄 Upsert (update or insert)
+// Note: Upsert is handled automatically by save() - if document exists it updates, otherwise inserts
+await foundUser.save();
+
+// 🗑️ Delete
+await foundUser.delete();
 ```

+## 🔥 Advanced Features
+
+### 🔎 Powerful Search Engine
+
+SmartData includes a Lucene-style search engine with automatic field indexing:
 
 ```typescript
-// Fetch a single user by a unique attribute
-const user = await User.getInstance({ username: 'myUsername' });
-
-// Fetch multiple users that match criteria
-const users = await User.getInstances({ email: 'myEmail@example.com' });
-
-// Using a cursor for large collections
-const cursor = await User.getCursor({ active: true });
-
-// Process documents one at a time (memory efficient)
-await cursor.forEach(async (user, index) => {
-  // Process each user with its position
-  console.log(`Processing user ${index}: ${user.username}`);
-});
-
-// Chain cursor methods like in the MongoDB native driver
-const paginatedCursor = await User.getCursor({ active: true })
-  .limit(10) // Limit results
-  .skip(20) // Skip first 20 results
-  .sort({ createdAt: -1 }); // Sort by creation date descending
-
-// Convert cursor to array (when you know the result set is small)
-const userArray = await paginatedCursor.toArray();
-
-// Other cursor operations
-const nextUser = await cursor.next(); // Get the next document
-const hasMoreUsers = await cursor.hasNext(); // Check if more documents exist
-const count = await cursor.count(); // Get the count of documents in the cursor
-
-// Always close cursors when done with them
-await cursor.close();
-```
-
-#### Update
-
-```typescript
-// Assuming 'user' is an instance of User
-user.email = 'newEmail@example.com';
-await user.save(); // Update the user in the database
-
-// Upsert operations (insert if not exists, update if exists)
-const upsertedUser = await User.upsert(
-  { id: 'user-123' }, // Query to find the user
-  {
-    // Fields to update or insert
-    username: 'newUsername',
-    email: 'newEmail@example.com',
-  },
-);
-```
-
-#### Delete
-
-```typescript
-// Assuming 'user' is an instance of User
-await user.delete(); // Delete the user from the database
-```
-
-## Advanced Features
-
-### Search Functionality
-
-SmartData provides powerful search capabilities with a Lucene-like query syntax and robust fallback mechanisms:
-
-```typescript
-// Define a model with searchable fields
 @Collection(() => db)
 class Product extends SmartDataDbDoc<Product, Product> {
-  @unI()
+  @unI() public id: string;
-  public id: string = 'product-id';
+  @svDb() @searchable() public name: string;
-
+  @svDb() @searchable() public description: string;
-  @svDb()
+  @svDb() @searchable() public category: string;
-  @searchable() // Mark this field as searchable
+  @svDb() public price: number;
-  public name: string;
-
-  @svDb()
-  @searchable() // Mark this field as searchable
-  public description: string;
-
-  @svDb()
-  @searchable() // Mark this field as searchable
-  public category: string;
-
-  @svDb()
-  public price: number;
 }
 
-// Get all fields marked as searchable for a class
+// 🎯 Exact phrase search
-const searchableFields = getSearchableFields('Product'); // ['name', 'description', 'category']
+await Product.search('"MacBook Pro 16"');
 
-// Basic search across all searchable fields
+// 🔤 Wildcard search
-const iPhoneProducts = await Product.searchWithLucene('iPhone');
+await Product.search('Mac*');
 
-// Field-specific search
+// 📁 Field-specific search
-const electronicsProducts = await Product.searchWithLucene('category:Electronics');
+await Product.search('category:Electronics');
 
-// Search with wildcards
+// 🧮 Boolean operators
-const macProducts = await Product.searchWithLucene('Mac*');
+await Product.search('(laptop OR desktop) AND NOT gaming');
 
-// Search in specific fields with partial words
+// 🔐 Secure multi-field search
-const laptopResults = await Product.searchWithLucene('description:laptop');
+await Product.search('TypeScript MongoDB'); // Automatically escaped
 
-// Search is case-insensitive
+// 🏷️ Scoped search with filters
-const results1 = await Product.searchWithLucene('electronics');
+await Product.search('laptop', {
-const results2 = await Product.searchWithLucene('Electronics');
+  filter: { price: { $lt: 2000 } },
-// results1 and results2 will contain the same documents
+  validate: (p) => p.inStock === true
-
+});
-// Using boolean operators (requires text index in MongoDB)
-const wirelessOrLaptop = await Product.searchWithLucene('wireless OR laptop');
-
-// Negative searches
-const electronicsNotSamsung = await Product.searchWithLucene('Electronics NOT Samsung');
-
-// Phrase searches
-const exactPhrase = await Product.searchWithLucene('"high-speed blender"');
-
-// Grouping with parentheses
-const complexQuery = await Product.searchWithLucene('(wireless OR bluetooth) AND Electronics');
 ```
 
-The search functionality includes:
+### 💾 EasyStore - Type-Safe Key-Value Storage
 
-- `@searchable()` decorator for marking fields as searchable
+Perfect for configuration, caching, and shared state:
-- `getSearchableFields()` to retrieve all searchable fields for a class
-- `search()` method for basic search (requires MongoDB text index)
-- `searchWithLucene()` method with robust fallback mechanisms
-- Support for field-specific searches, wildcards, and boolean operators
-- Automatic fallback to regex-based search if MongoDB text search fails
-
-### EasyStore
-
-EasyStore provides a simple key-value storage system with automatic persistence:
 
 ```typescript
-// Create an EasyStore instance with a specific type
+interface AppConfig {
-interface ConfigStore {
   apiKey: string;
-  settings: {
+  features: {
-    theme: string;
+    darkMode: boolean;
     notifications: boolean;
   };
+  limits: {
+    maxUsers: number;
+    maxStorage: number;
+  };
 }
 
-// Create a type-safe EasyStore
+// Create a type-safe store
-const store = await db.createEasyStore<ConfigStore>('app-config');
+const config = await db.createEasyStore<AppConfig>('app-config');
 
-// Write and read data with full type safety
+// Write with full IntelliSense
-await store.writeKey('apiKey', 'secret-api-key-123');
+await config.writeKey('features', {
-await store.writeKey('settings', { theme: 'dark', notifications: true });
+  darkMode: true,
+  notifications: false
+});
 
-const apiKey = await store.readKey('apiKey'); // Type: string
+// Read with guaranteed types
-const settings = await store.readKey('settings'); // Type: { theme: string, notifications: boolean }
+const features = await config.readKey('features');
+// TypeScript knows: features.darkMode is boolean
 
-// Check if a key exists
+// Atomic operations
-const hasKey = await store.hasKey('apiKey'); // true
+await config.writeAll({
+  apiKey: 'new-key',
+  limits: { maxUsers: 1000, maxStorage: 5000 }
+});
 
 // Delete a key
-await store.deleteKey('apiKey');
+await config.deleteKey('features');
+
+// Wipe entire store
+await config.wipe();
 ```
 
-### Distributed Coordination
+### 🌐 Distributed Coordination
 
-Built-in support for distributed systems with leader election:
+Build resilient distributed systems with automatic leader election:
 
 ```typescript
-// Create a distributed coordinator
 const coordinator = new SmartdataDistributedCoordinator(db);
 
-// Start coordination
+// Start coordination with automatic heartbeat
 await coordinator.start();
 
-// Handle leadership changes
+// Check if this instance is the leader
-coordinator.on('leadershipChange', (isLeader) => {
+const eligibleLeader = await coordinator.getEligibleLeader();
+const isLeader = eligibleLeader?.id === coordinator.id;
+
 if (isLeader) {
-    // This instance is now the leader
+  console.log('🎖️ This instance is now the leader!');
-    // Run leader-specific tasks
+  // Leader-specific tasks are handled internally by leadFunction()
-    startPeriodicJobs();
+  // The coordinator automatically manages leader election and failover
-  } else {
-    // This instance is no longer the leader
-    stopPeriodicJobs();
-  }
-});
-
-// Access leadership status anytime
-if (coordinator.isLeader) {
-  // Run leader-only operations
 }
 
-// Execute a task only on the leader
+// Fire distributed task requests (for taskbuffer integration)
-await coordinator.executeIfLeader(async () => {
+const result = await coordinator.fireDistributedTaskRequest({
-  // This code only runs on the leader instance
+  taskName: 'maintenance',
-  await runImportantTask();
+  taskExecutionTime: Date.now(),
+  requestResponseId: 'unique-id'
 });
 
-// Stop coordination when shutting down
+// Graceful shutdown
 await coordinator.stop();
 ```
 
-### Real-time Data Watching
+### 📡 Real-Time Change Streams
 
-Watch for changes in your collections with RxJS integration using MongoDB Change Streams:
+React to database changes instantly with RxJS integration:
 
 ```typescript
-// Create a watcher for a specific collection with a query filter
+// Watch for specific changes
 const watcher = await User.watch(
+  { active: true },  // Only watch active users
   {
-    active: true, // Only watch for changes to active users
+    fullDocument: 'updateLookup',  // Include full document
-  },
+    bufferTimeMs: 100,  // Buffer for performance
-  {
+  }
-    fullDocument: true, // Include the full document in change notifications
-    bufferTimeMs: 100, // Buffer changes for 100ms to reduce notification frequency
-  },
 );
 
-// Subscribe to changes using RxJS
+// Subscribe with RxJS (emits documents or arrays if buffered)
-watcher.changeSubject.subscribe((change) => {
+watcher.changeSubject
-  console.log('Change operation:', change.operationType); // 'insert', 'update', 'delete', etc.
+  .pipe(
-  console.log('Document changed:', change.docInstance); // The full document instance
+    filter(user => user !== null),  // Filter out deletions
+  )
+  .subscribe(user => {
+    console.log(`📢 User change detected: ${user.username}`);
+    sendNotification(user.email);
+  });
 
-  // Handle different types of changes
+// Or use EventEmitter pattern
-  if (change.operationType === 'insert') {
+watcher.on('change', (user) => {
-    console.log('New user created:', change.docInstance.username);
+  if (user) {
-  } else if (change.operationType === 'update') {
+    console.log(`✏️ User changed: ${user.username}`);
-    console.log('User updated:', change.docInstance.username);
+  } else {
-  } else if (change.operationType === 'delete') {
+    console.log(`👋 User deleted`);
-    console.log('User deleted');
   }
 });
 
-// Manual observation with event emitter pattern
+// Clean up when done
-watcher.on('change', (change) => {
-  console.log('Document changed:', change);
-});
-
-// Stop watching when no longer needed
 await watcher.stop();
 ```
 
-### Managed Collections
+### 🎯 Cursor Operations for Large Datasets
 
-For more complex data models that require additional context:
+Handle millions of documents efficiently:
 
 ```typescript
-@Collection(() => db)
+// Create a cursor with modifiers
-class ManagedDoc extends SmartDataDbDoc<ManagedDoc, ManagedDoc> {
+const cursor = await User.getCursor(
-  @unI()
+  { active: true },
-  public id: string = 'unique-id';
+  { 
-
+    modifier: (cursor) => cursor
-  @svDb()
+      .sort({ createdAt: -1 })
-  public data: string;
+      .skip(100)
-
+      .limit(50)
-  @managed()
-  public manager: YourCustomManager;
-
-  // The manager can provide additional functionality
-  async specialOperation() {
-    return this.manager.doSomethingSpecial(this);
   }
+);
+
+// Stream processing - memory efficient
+await cursor.forEach(async (user) => {
+  await processUser(user);
+  // Processes one at a time, minimal memory usage
+});
+
+// Manual iteration
+let user;
+while (user = await cursor.next()) {
+  if (shouldStop(user)) {
+    break;
   }
+  await handleUser(user);
+}
+
+// Convert to array (only for small datasets!)
+const users = await cursor.toArray();
+
+// Always clean up
+await cursor.close();
 ```
 
-### Automatic Indexing
+### 🔐 Transaction Support
 
-Define indexes directly in your model class:
+Ensure data consistency with MongoDB transactions:
 
 ```typescript
-@Collection(() => db)
+const session = db.startSession();
-class Product extends SmartDataDbDoc<Product, Product> {
-  @unI() // Unique index
-  public id: string = 'product-id';
 
-  @svDb()
-  @index() // Regular index for faster queries
-  public category: string;
-
-  @svDb()
-  @index({ sparse: true }) // Sparse index with options
-  public optionalField?: string;
-
-  // Compound indexes can be defined in the collection decorator
-  @Collection(() => db, {
-    indexMap: {
-      compoundIndex: {
-        fields: { category: 1, name: 1 },
-        options: { background: true }
-      }
-    }
-  })
-}
-```
-
-### Transaction Support
-
-Use MongoDB transactions for atomic operations:
-
-```typescript
-const session = await db.startSession();
 try {
   await session.withTransaction(async () => {
-    const user = await User.getInstance({ id: 'user-id' }, { session });
+    // All operations in this block are atomic
-    user.balance -= 100;
+    const sender = await User.getInstance(
-    await user.save({ session });
+      { id: 'user-1' }, 
+      session  // Pass session to all operations
+    );
+    sender.balance -= 100;
+    await sender.save({ session });
     
-    const recipient = await User.getInstance({ id: 'recipient-id' }, { session });
+    const receiver = await User.getInstance(
-    recipient.balance += 100;
+      { id: 'user-2' }, 
-    await user.save({ session });
+      session
+    );
+    receiver.balance += 100;
+    await receiver.save({ session });
+    
+    // If anything fails, everything rolls back
+    if (sender.balance < 0) {
+      throw new Error('Insufficient funds!');
+    }
   });
+  
+  console.log('✅ Transaction completed successfully');
+} catch (error) {
+  console.error('❌ Transaction failed, rolled back');
 } finally {
   await session.endSession();
 }
 ```
 
-### Deep Object Queries
+### 🎨 Custom Serialization
 
-SmartData provides fully type-safe deep property queries with the `DeepQuery` type:
+Handle complex data types with custom serializers:
 
 ```typescript
-// If your document has nested objects
+class Document extends SmartDataDbDoc<Document, Document> {
-class UserProfile extends SmartDataDbDoc<UserProfile, UserProfile> {
+  @svDb({
-  @unI()
+    // Encrypt sensitive data before storing
-  public id: string = 'profile-id';
+    serialize: async (value) => {
-
+      return await encrypt(value);
-  @svDb()
+    },
-  public user: {
+    // Decrypt when reading
-    details: {
+    deserialize: async (value) => {
-      firstName: string;
+      return await decrypt(value);
-      lastName: string;
-      address: {
-        city: string;
-        country: string;
-      };
-    };
-  };
     }
+  })
+  public sensitiveData: string;
   
-// Type-safe string literals for dot notation
+  @svDb({
-const usersInUSA = await UserProfile.getInstances({
+    // Compress large JSON objects
-  'user.details.address.country': 'USA',
+    serialize: (value) => compress(JSON.stringify(value)),
-});
+    deserialize: (value) => JSON.parse(decompress(value))
+  })
+  public largePayload: any;
   
-// Fully typed deep queries with the DeepQuery type
+  @svDb({
-import { DeepQuery } from '@push.rocks/smartdata';
+    // Store sets as arrays
-
+    serialize: (set) => Array.from(set),
-const typedQuery: DeepQuery<UserProfile> = {
+    deserialize: (arr) => new Set(arr)
-  id: 'profile-id',
+  })
-  'user.details.firstName': 'John',
+  public tags: Set<string>;
-  'user.details.address.country': 'USA',
+}
-};
-
-// TypeScript will error if paths are incorrect
-const results = await UserProfile.getInstances(typedQuery);
-
-// MongoDB query operators are supported
-const operatorQuery: DeepQuery<UserProfile> = {
-  'user.details.address.country': 'USA',
-  'user.details.address.city': { $in: ['New York', 'Los Angeles'] },
-};
-
-const filteredResults = await UserProfile.getInstances(operatorQuery);
 ```
 
-### Document Lifecycle Hooks
+### 🎣 Lifecycle Hooks
 
-Implement custom logic at different stages of a document's lifecycle:
+Add custom logic at any point in the document lifecycle:
 
 ```typescript
 @Collection(() => db)
 class Order extends SmartDataDbDoc<Order, Order> {
-  @unI()
+  @unI() public id: string;
-  public id: string = 'order-id';
+  @svDb() public items: OrderItem[];
+  @svDb() public total: number;
+  @svDb() public status: 'pending' | 'paid' | 'shipped';
   
-  @svDb()
+  // Validate and calculate before saving
-  public total: number;
-
-  @svDb()
-  public items: string[];
-
-  // Called before saving the document
   async beforeSave() {
-    // Calculate total based on items
+    this.total = this.items.reduce((sum, item) => 
-    this.total = await calculateTotal(this.items);
+      sum + (item.price * item.quantity), 0
+    );
     
-    // Validate the document
     if (this.items.length === 0) {
-      throw new Error('Order must have at least one item');
+      throw new Error('Order must have items!');
     }
   }
   
-  // Called after the document is saved
+  // Send notifications after saving
   async afterSave() {
-    // Notify other systems about the saved order
+    if (this.status === 'paid') {
-    await notifyExternalSystems(this);
+      await sendOrderConfirmation(this);
+      await notifyWarehouse(this);
+    }
   }
   
-  // Called before deleting the document
+  // Prevent deletion of shipped orders
   async beforeDelete() {
-    // Check if order can be deleted
+    if (this.status === 'shipped') {
-    const canDelete = await checkOrderDeletable(this.id);
+      throw new Error('Cannot delete shipped orders!');
-    if (!canDelete) {
-      throw new Error('Order cannot be deleted');
     }
   }
+  
+  // Audit logging
+  async afterDelete() {
+    await auditLog.record({
+      action: 'order_deleted',
+      orderId: this.id,
+      timestamp: new Date()
+    });
+  }
 }

+### 🔍 Deep Query Type Safety
+
+TypeScript knows your nested object structure:
+
+```typescript
+interface UserProfile {
+  personal: {
+    name: {
+      first: string;
+      last: string;
+    };
+    age: number;
+  };
+  address: {
+    street: string;
+    city: string;
+    country: string;
+  };
+}
+
+@Collection(() => db)
+class Profile extends SmartDataDbDoc<Profile, Profile> {
+  @unI() public id: string;
+  @svDb() public data: UserProfile;
+}
+
+// TypeScript enforces correct paths and types!
+const profiles = await Profile.getInstances({
+  'data.personal.name.first': 'John',  // ✅ Type-checked
+  'data.address.country': 'USA',       // ✅ Type-checked
+  'data.personal.age': { $gte: 18 },   // ✅ Type-checked
+  // 'data.invalid.path': 'value'      // ❌ TypeScript error!
+});
+```
+
+## 🛡️ Security Features
+
+SmartData includes enterprise-grade security out of the box:
+
+- **🔐 Credential Security**: Automatic encoding of special characters in passwords
+- **💉 Injection Prevention**: NoSQL injection protection with query sanitization
+- **🚫 Dangerous Operator Blocking**: Prevents use of `$where` and other risky operators
+- **🔒 Secure Defaults**: Production-ready connection settings out of the box
+- **🛑 Rate Limiting Ready**: Built-in connection pooling prevents connection exhaustion
+
+## 🎯 Best Practices
 
 ### Connection Management
+```typescript
+// ✅ DO: Use connection pooling options
+const db = new SmartdataDb({
+  mongoDbUrl: 'mongodb://localhost:27017/myapp',
+  maxPoolSize: 50,  // Adjust based on your load
+  maxIdleTimeMS: 300000  // 5 minutes
+});
 
-- Always call `db.init()` before using any database features
+// ✅ DO: Always close connections on shutdown
-- Use `db.disconnect()` when shutting down your application
+process.on('SIGTERM', async () => {
-- Set appropriate connection pool sizes based on your application's needs
+  await db.close();
+  process.exit(0);
+});
 
-### Document Design
+// ❌ DON'T: Create multiple DB instances for the same database
-
+```
-- Use appropriate decorators (`@svDb`, `@unI`, `@index`, `@searchable`) to optimize database operations
-- Implement type-safe models by properly extending `SmartDataDbDoc`
-- Consider using interfaces to define document structures separately from implementation
-- Mark fields that need to be searched with the `@searchable()` decorator
-
-### Search Optimization
-
-- Create MongoDB text indexes for collections that need advanced search operations
-- Use `searchWithLucene()` for robust searches with fallback mechanisms
-- Prefer field-specific searches when possible for better performance
-- Use simple term queries instead of boolean operators if you don't have text indexes
 
 ### Performance Optimization
+```typescript
+// ✅ DO: Use cursors for large datasets
+const cursor = await LargeCollection.getCursor({});
+await cursor.forEach(async (doc) => {
+  await processDocument(doc);
+});
 
-- Use cursors for large datasets instead of loading all documents into memory
+// ❌ DON'T: Load everything into memory
-- Create appropriate indexes for frequent query patterns
+const allDocs = await LargeCollection.getInstances({}); // Could OOM!
-- Use projections to limit the fields returned when you don't need the entire document
 
-### Distributed Systems
+// ✅ DO: Create indexes for frequent queries
+@index() public frequentlyQueried: string;
 
-- Implement proper error handling for leader election events
+// ✅ DO: Use projections when you don't need all fields
-- Ensure all instances have synchronized clocks when using time-based coordination
+const cursor = await User.getCursor(
-- Use the distributed coordinator's task management features for coordinated operations
+  { active: true },
+  { projection: { username: 1, email: 1 } }
+);
+```
 
 ### Type Safety
+```typescript
+// ✅ DO: Leverage TypeScript's type system
+interface StrictUserData {
+  verified: boolean;
+  roles: ('admin' | 'user' | 'guest')[];
+}
 
-- Take advantage of the `DeepQuery<T>` type for fully type-safe queries
+@Collection(() => db)
-- Define proper types for your document models to enhance IDE auto-completion
+class StrictUser extends SmartDataDbDoc<StrictUser, StrictUser> {
-- Use generic type parameters to specify exact document types when working with collections
+  @svDb() public data: StrictUserData;  // Fully typed!
+}
