### URL Filtering

```java
// Include patterns
crawler.urlFilter.addInclude("https://example.com/.*");
crawler.urlFilter.addInclude(".*\\.pdf$");

// Exclude patterns  
crawler.urlFilter.addExclude(".*\\.js$");
crawler.urlFilter.addExclude(".*login.*");
```

## Architecture Patterns

### Action (Controller)
- Hierarchy: `TypicalAction` → `FessBaseAction` → `FessAdminAction`/`FessSearchAction`
- `@Execute` marks web endpoints
- `@Resource` for DI
