## 📖 Usage

### Basic Usage

```python
from indianconstitution import IndianConstitution

# Initialize
india = IndianConstitution()

# Access the Preamble
print(india.preamble())

# Get a specific article
print(india.get_article(14))

# Search for articles
print(india.search_keyword('equality'))

# Count articles
print(f"Total articles: {india.count_articles()}")
```

### Advanced Usage

#### DataFrame Support (pandas-like interface)

```python
import pandas as pd
from indianconstitution import IndianConstitution

india = IndianConstitution()

# Convert to DataFrame
df = india.to_dataframe()

# Use pandas operations
print(df.head())
print(df.describe())

# Filter articles
fundamental_rights = df[df['title'].str.contains('Fundamental', case=False)]
print(fundamental_rights[['article', 'title', 'word_count']])

# Sort by word count
longest_articles = df.nlargest(10, 'word_count')
print(longest_articles[['article', 'title', 'word_count']])
```

#### Advanced Search

```python
# Regex search
results = india.search_regex(r'\b(equality|liberty|fraternity)\b', case_sensitive=False)
for article in results:
    print(f"Article {article['article']}: {article['title']}")

# Fuzzy search (handles typos and partial matches)
results = india.fuzzy_search('fundamental rights', threshold=70, limit=10)
for article in results:
    print(f"Article {article['article']}: {article['title']}")
```

#### Export Functionality

```python
# Export to JSON
india.export_json('constitution.json')

# Export to CSV (requires pandas)
india.export_csv('constitution.csv')

# Export to Markdown
india.export_markdown('constitution.md')
```

#### Statistical Analysis

```python
# Get comprehensive statistics
stats = india.get_statistics()
print(f"Total Articles: {stats['total_articles']}")
print(f"Total Words: {stats['total_words']:,}")
print(f"Average Words per Article: {stats['average_words_per_article']}")
print(f"Longest Article: {stats['longest_article']['title']}")
```
