```

## 🚀 **Quick Start**

### **Basic Usage**
```javascript
const TDKSozluk = require('creart-tdk');

// Create instance
const tdk = new TDKSozluk();

// Search word
const result = await tdk.ara('merhaba');
console.log(result.data.kelime); // "merhaba"
console.log(result.data.anlamlar); // Meanings array
```

### **Asterisk Search (NEW!)**
```javascript
// Wildcard search: "k?tap" finds words like "kitap", "katap"
const wildcardResult = await tdk.asteriskAra('k?tap');

// Multiple unknowns: "k???p" finds 5-letter words
const multiResult = await tdk.asteriskAra('k???p');

// Length specific: "k*p,5" finds 5-letter k...p words
const lengthResult = await tdk.asteriskAra('k*p,5');
```

### **Spell Checking (NEW!)**
```javascript
const spellCheck = await tdk.yazimDenetimi('Türkçe yazım öreneği');
console.log(spellCheck.data.istatistik.dogrulukOrani); // 75%
console.log(spellCheck.data.sonuclar[3].oneriler); // ["örneği", "örnek", "ören"]
```

## 📖 **Complete Usage Examples**

### **1. Full Feature Usage**
```javascript
const TDKSozluk = require('creart-tdk');
const tdk = new TDKSozluk({
  cache: true,
  timeout: 15000
});

// Word search with all features
const wordResult = await tdk.ara('kitap', {
  telaffuz: true,          // Include pronunciation
  cacheTTL: 3600          // Cache for 1 hour
});

// Get today's word
const dailyWord = await tdk.gununKelimesi();

const pronunciation = await tdk.sesGetir('merhaba');
```

### **2. API Server Usage**

  corsOrigin: 'https://yourdomain.com',
  rateLimitMax: 100,
  tdk: {
    cache: true,
    timeout: 20000
  }
});
```

## 🔧 **Advanced Configuration**

### **Class Options**
```javascript
const tdk = new TDKSozluk({
  baseURL: 'https://sozluk.gov.tr/',
  timeout: 15000,          // Request timeout
  retryCount: 3,          // Retry attempts
  cache: true,           // Enable caching
  // ... other options
});
```

### **Search Options**
```javascript
const result = await tdk.ara('kelime', {
  telaffuz: true,        // Include pronunciation
  cacheTTL: 1800,        // Cache time in seconds
  // Advanced options...
});
```

## 🎯 **Asterisk Search Patterns**

### **Pattern Examples:**
```
k?tap     → Matches: "kitap", "katap", "kutap"
k???p     → Matches 5-letter words: "kalıp", "künyep"
a*a       → Matches: "ada", "araba", "aşkla"
k*p,5     → Matches 5-letter words: "kalıp", "kavup"
?e?me     → Matches: "gelme", "değme", "seçme"
```

### **Pattern Rules:**
- `?` - Any single character
- `*` - Any number of characters (including zero)
- `,` - Length specifier (e.g., `,5` for 5 letters)
- Case insensitive
- Turkish character support
