 # Changelog
 
+## 2025-04-23 - 5.14.0 - feat(doc)
+Implement support for beforeSave, afterSave, beforeDelete, and afterDelete lifecycle hooks in document save and delete operations to allow custom logic execution during these critical moments.
+
+- Calls beforeSave hook if defined before performing insert or update.
+- Calls afterSave hook after a document is saved.
+- Calls beforeDelete hook before deletion and afterDelete hook afterward.
+- Ensures _updatedAt timestamp is refreshed during save operations.
+
+## 2025-04-22 - 5.13.1 - fix(search)
+Improve search query parsing for implicit AND queries by preserving quoted substrings and better handling free terms, quoted phrases, and field:value tokens.
+
+- Replace previous implicit AND logic with tokenization that preserves quoted substrings
+- Support both free term and field:value tokens with wildcards inside quotes
+- Ensure errors are thrown for non-searchable fields in field-specific queries
+
+## 2025-04-22 - 5.13.0 - feat(search)
+Improve search query handling and update documentation
+
+- Added 'codex.md' providing a high-level project overview and detailed search API documentation.
+- Enhanced search parsing in SmartDataDbDoc to support combined free-term and quoted field phrase queries.
+- Introduced a new fallback branch in the search method to handle free term with quoted field input.
+- Updated tests in test/test.search.ts to cover new combined query scenarios and ensure robust behavior.
+
+## 2025-04-22 - 5.12.2 - fix(search)
+Fix handling of quoted wildcard patterns in field-specific search queries and add tests for location-based wildcard phrase searches
+
+- Strip surrounding quotes from wildcard patterns in field queries to correctly transform them to regex
+- Introduce new tests in test/test.search.ts to validate exact quoted and unquoted wildcard searches on a location field
+
 ## 2025-04-22 - 5.12.1 - fix(search)
 Improve implicit AND logic for mixed free term and field queries in search and enhance wildcard field handling.

+# 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 });
+```
