-### Basic String Matching
+### 🔍 Smart String Matching

-For scenarios where you have an array of strings and you wish to find a match for a search term:
+Perfect for autocomplete, spell-check, or finding the best match from a list:

 ```typescript
 const myDictionary = ['Sony', 'Deutsche Bahn', 'Apple Inc.', "Trader Joe's"];
@@ -47,11 +119,11 @@ console.log(scores);

 This example demonstrates how to instantiate the `Smartfuzzy` class with a list of strings (dictionary) and add more entries to it. You can then use it to find the closest match or calculate similarity scores for a given search string.

-> **Note:** The older method names `getClosestMatchForString` and `getChangeScoreForString` are still available for backward compatibility but are deprecated. It's recommended to use the new method names `findClosestMatch` and `calculateScores` instead.

-### Advanced Object Sorting

-Imagine you are managing a list of objects, and you wish to sort them based on the resemblance of one or more of their properties to a search term:
+### 📊 Intelligent Object Sorting
+
+Transform any object array into a smart, searchable dataset:

 ```typescript
 interface ICar {

 This scenario shows how to use `ObjectSorter` for sorting an array of objects based on how closely one of their string properties matches a search term. This is particularly useful for filtering or autocomplete features where relevance is key.

-### Searching Within Articles
+### 📄 Powerful Content Search

-If your application involves searching through articles or similar textual content, `ArticleSearch` allows for a weighted search across multiple fields:
+Build sophisticated search experiences for articles, blog posts, or any content with multiple fields:

 import { IArticle } from '@tsclass/tsclass/content';
@@ -109,11 +181,455 @@ console.log(searchResult); // Array of matches with relevance to 'rich history'

 The `ArticleSearch` class showcases how to implement a search feature across a collection of articles with prioritization across different fields (e.g., title, content, tags). This ensures more relevant search results and creates a better experience for users navigating through large datasets or content libraries.

-### Conclusion
+## 🔥 Real-World Use Cases

-`@push.rocks/smartfuzzy` offers a robust set of functionalities for integrating fuzzy searching and sorting capabilities into your TypeScript applications. By following the examples demonstrated, you can effectively utilize the module to enhance user experience where text search is a critical component of the application.
+### Search-as-You-Type
+Build responsive search experiences:

-Remember to always consider the specific requirements of your project when implementing these features, as adjustments to configurations such as threshold levels and keys to search on can significantly impact the effectiveness of your search functionality.
+```typescript
+import { Smartfuzzy } from '@push.rocks/smartfuzzy';
+
+const cities = ['New York', 'Los Angeles', 'Chicago', 'Houston', 'Phoenix'];
+const citySearch = new Smartfuzzy(cities);
+
+// User types "new yo"
+const suggestions = citySearch.calculateScores('new yo');
+// Returns: { 'New York': 2, 'Los Angeles': 8, ... }
+
+// Show top 3 suggestions
+const topSuggestions = Object.entries(suggestions)
+  .sort(([,a], [,b]) => a - b)
+  .slice(0, 3)
+  .map(([city]) => city);
+```
+
+### Data Deduplication
+Clean up messy datasets:
+
+```typescript
+import { ObjectSorter } from '@push.rocks/smartfuzzy';
+
+const contacts = [
+  { name: 'John Smith', email: 'john@example.com' },
+  { name: 'Jon Smith', email: 'jon.smith@example.com' },  // Likely duplicate
+  { name: 'Jane Doe', email: 'jane@example.com' }
+];
+
+const sorter = new ObjectSorter(contacts);
+
+// Find potential duplicates for each contact
+contacts.forEach(contact => {
+  const matches = sorter.sort(contact.name, ['name']);
+  if (matches.length > 1 && matches[0].score < 0.3) {
+    console.log(`Potential duplicate: ${contact.name} ↔ ${matches[1].item.name}`);
+  }
+});
+```
+
+### Smart Product Search
+E-commerce search with typo tolerance:
+
+```typescript
+import { ObjectSorter } from '@push.rocks/smartfuzzy';
+
+const products = [
+  { name: 'iPhone 15 Pro', category: 'Electronics', brand: 'Apple' },
+  { name: 'MacBook Air', category: 'Computers', brand: 'Apple' },
+  { name: 'AirPods Pro', category: 'Audio', brand: 'Apple' }
+];
+
+const productSearch = new ObjectSorter(products);
+
+// User searches "macbok air" (with typos)
+const results = productSearch.sort('macbok air', ['name', 'brand']);
+// Correctly finds "MacBook Air" despite typos
+```
+
+### Recommendation System
+Content-based recommendations:
+
+```typescript
+import { ArticleSearch } from '@push.rocks/smartfuzzy';
+
+const articles = [
+  { title: 'React Hooks Guide', tags: ['react', 'javascript'], content: '...' },
+  { title: 'Vue.js Tutorial', tags: ['vue', 'javascript'], content: '...' },
+  { title: 'Angular Components', tags: ['angular', 'typescript'], content: '...' }
+];
+
+const articleSearch = new ArticleSearch(articles);
+
+// User reads about React, find similar content
+const similar = await articleSearch.search('react javascript hooks');
+// Returns articles ordered by relevance
+```
+
+## 🚨 Error Handling
+
+SmartFuzzy provides clear error messages and graceful degradation:
+
+### Input Validation
+```typescript
+import { Smartfuzzy } from '@push.rocks/smartfuzzy';
+
+const fuzzy = new Smartfuzzy(['apple', 'banana']);
+
+try {
+  // ❌ This will throw an error
+  const result = fuzzy.findClosestMatch(123 as any);
+} catch (error) {
+  console.error('Error:', error.message); // "Input must be a string"
+}
+```
+
+### Graceful Degradation
+```typescript
+// Empty dictionary returns null instead of throwing
+const emptyFuzzy = new Smartfuzzy([]);
+const result = emptyFuzzy.findClosestMatch('test'); // Returns: null
+
+// Empty object array returns empty results
+const emptyObjectSorter = new ObjectSorter([]);
+const results = emptyObjectSorter.sort('test', ['name']); // Returns: []
+```
+
+### Best Practices
+```typescript
+import { Smartfuzzy, ObjectSorter } from '@push.rocks/smartfuzzy';
+
+// ✅ Always validate your inputs
+function safeSearch(query: unknown, dictionary: string[]) {
+  if (typeof query !== 'string') {
+    return null; // Or throw a custom error
+  }
+  
+  if (!Array.isArray(dictionary) || dictionary.length === 0) {
+    return null;
+  }
+  
+  const fuzzy = new Smartfuzzy(dictionary);
+  return fuzzy.findClosestMatch(query);
+}
+
+// ✅ Handle async operations properly
+async function searchArticles(query: string, articles: IArticle[]) {
+  try {
+    const search = new ArticleSearch(articles);
+    const results = await search.search(query);
+    return results;
+  } catch (error) {
+    console.error('Search failed:', error);
+    return []; // Return empty results on error
+  }
+}
+```

+---
+
+## ⚡ Performance Guide
+
+### Time Complexity
+- **Smartfuzzy.findClosestMatch**: O(n × m) where n = dictionary size, m = average string length
+- **ObjectSorter.sort**: O(n × k × m) where k = number of keys to search
+- **ArticleSearch.search**: O(n × f × m) where f = number of fields (title, content, tags)
+
+### Recommended Dataset Sizes
+- **Small (< 1,000 items)**: Excellent performance, sub-millisecond responses
+- **Medium (1,000 - 10,000 items)**: Good performance, 1-10ms responses  
+- **Large (10,000+ items)**: Consider chunking or server-side search for real-time UIs
+
+### Optimization Tips
+
+#### 1. Reuse Instances
+```typescript
+// ✅ Good: Reuse the same instance
+const fuzzy = new Smartfuzzy(largeDictionary);
+const result1 = fuzzy.findClosestMatch('query1');
+const result2 = fuzzy.findClosestMatch('query2');
+
+// ❌ Avoid: Creating new instances repeatedly
+const result1 = new Smartfuzzy(largeDictionary).findClosestMatch('query1');
+const result2 = new Smartfuzzy(largeDictionary).findClosestMatch('query2');
+```
+
+#### 2. Batch Operations
+```typescript
+// ✅ Good: Calculate scores once, extract multiple matches
+const scores = fuzzy.calculateScores('query');
+const topMatches = Object.entries(scores)
+  .sort(([,a], [,b]) => a - b)
+  .slice(0, 5);
+
+// ❌ Avoid: Multiple separate lookups
+const match1 = fuzzy.findClosestMatch('query');
+const match2 = fuzzy.findClosestMatch('query'); // Duplicate work
+```
+
+#### 3. Optimize Search Keys
+```typescript
+// ✅ Good: Search only necessary fields
+const results = sorter.sort('query', ['name']); // Fast
+
+// ❌ Avoid: Searching unnecessary fields
+const results = sorter.sort('query', ['name', 'description', 'notes']); // Slower
+```
+
+#### 4. Memory Management
+```typescript
+// For very large datasets, consider chunking
+function chunkedSearch(query: string, largeArray: any[], chunkSize = 1000) {
+  const results = [];
+  
+  for (let i = 0; i < largeArray.length; i += chunkSize) {
+    const chunk = largeArray.slice(i, i + chunkSize);
+    const sorter = new ObjectSorter(chunk);
+    results.push(...sorter.sort(query, ['name']));
+  }
+  
+  return results.sort((a, b) => a.score - b.score);
+}
+```
+
+### Advanced Configuration
+
+#### Custom Fuse.js Options
+
+**Current Implementation**: The Fuse.js options are optimized for general use cases:
+
+```typescript
+// Default configuration in SmartFuzzy
+const fuseOptions = {
+  shouldSort: true,
+  threshold: 0.6,        // 0.0 = exact match, 1.0 = match anything
+  location: 0,           // Start position for search
+  distance: 100,         // Search distance from location
+  maxPatternLength: 32,  // Maximum pattern length
+  minMatchCharLength: 1  // Minimum match character length
+};
+```
+
+**Configuration Guidelines**:
+- **threshold: 0.0-1.0** - Lower values require closer matches
+- **distance** - How far from `location` to search  
+- **location** - Where in the string to start searching (0 = beginning)
+
+#### Custom Matching Behavior
+
+While direct configuration isn't exposed yet, you can achieve custom behavior:
+
+```typescript
+// For stricter matching, filter results by score
+const fuzzy = new Smartfuzzy(['apple', 'application', 'apply']);
+const scores = fuzzy.calculateScores('app');
+
+// Only accept very close matches (score < 2)
+const strictMatches = Object.entries(scores)
+  .filter(([word, score]) => score < 2)
+  .sort(([,a], [,b]) => a - b);
+
+// For more lenient matching, use a higher threshold in your logic
+const lenientMatches = Object.entries(scores)
+  .filter(([word, score]) => score < 5)
+  .sort(([,a], [,b]) => a - b);
+```
+
+#### Article Search Weighting
+The ArticleSearch class uses intelligent field weighting:
+
+```typescript
+// Built-in weighting (not directly configurable)
+const searchWeights = {
+  title: 3,    // Highest priority - titles are most important
+  tags: 2,     // Medium priority - tags are descriptive
+  content: 1   // Lower priority - content can be lengthy
+};
+
+// This means a match in the title has 3x more relevance than content
+```
+

+## 🔍 Troubleshooting & FAQ
+
+### Common Issues
+
+#### "Cannot find module" errors
+```bash
+# Ensure you've installed the package
+pnpm install @push.rocks/smartfuzzy
+
+# For TypeScript projects, types are included automatically
+```
+
+#### Poor matching results
+```typescript
+// If matches seem inaccurate, check your input data
+const fuzzy = new Smartfuzzy(['apple', 'APPLE', 'Apple']);
+// Consider normalizing case before adding to dictionary
+const normalizedDict = ['apple', 'banana', 'orange'].map(s => s.toLowerCase());
+const fuzzy2 = new Smartfuzzy(normalizedDict);
+```
+
+#### Performance issues with large datasets
+```typescript
+// For > 10,000 items, consider limiting search scope
+const scores = fuzzy.calculateScores('query');
+const topResults = Object.entries(scores)
+  .sort(([,a], [,b]) => a - b)
+  .slice(0, 10); // Only get top 10 results
+```
+
+### FAQ
+
+**Q: Can I search case-insensitively?**
+A: SmartFuzzy is case-sensitive by default. Normalize your data:
+```typescript
+const fuzzy = new Smartfuzzy(dict.map(s => s.toLowerCase()));
+const result = fuzzy.findClosestMatch(query.toLowerCase());
+```
+
+**Q: How do I handle special characters?**
+A: Fuse.js handles Unicode well, but you may want to normalize:
+```typescript
+const normalize = (str: string) => str.normalize('NFD').replace(/[\u0300-\u036f]/g, '');
+```
+
+**Q: Can I weight object properties differently?**
+A: Currently not directly configurable, but you can post-process results:
+```typescript
+const results = sorter.sort(query, ['name', 'description']);
+// Boost results that matched 'name' field
+const boosted = results.map(r => ({
+  ...r,
+  score: r.matches?.some(m => m.key === 'name') ? r.score * 0.5 : r.score
+}));
+```
+
+**Q: What's the difference between `findClosestMatch` and `calculateScores`?**
+A: `findClosestMatch` returns only the best match, while `calculateScores` returns scores for all dictionary entries, letting you implement custom ranking logic.
+
+**Q: How do I handle empty results?**
+A: Always check for null/empty returns:
+```typescript
+const match = fuzzy.findClosestMatch('query');
+if (match === null) {
+  console.log('No suitable match found');
+}
+```
+
