# Searching and Filtering Books

## Tag-Based Filtering

Bookhoard uses Calibre's tag system for categorization. When you import books from Calibre, their tags are automatically available for filtering.

### How Tags Work

Tags are keywords or categories assigned to books, such as:
- **Genres:** Science Fiction, Fantasy, Mystery, Romance
- **Categories:** Favorites, To Read, Read
- **Metadata:** Ebook, Owned, Borrowed

### Filtering by Tags

1. Navigate to the **Bookshelf** page
2. Use the **Tags** filter input
3. Start typing to see autocomplete suggestions
4. Select a tag or press Enter to filter

**Example:** Typing "Sci" will suggest "Science Fiction"

### Combining Filters

You can combine tags with other filters:
- **Tags + Author:** Find all Science Fiction by Asimov
- **Tags + Series:** Find all Fantasy in the "Wheel of Time" series
- **Tags + Year:** Find all Dystopian fiction published after 2000

### Tips

- You can add custom tags when editing book metadata
