### Auto-Generated Files

Never edit these files manually (marked with `@author FreeGen`):
- `FessLabels.java`
- `FessMessages.java`

Always regenerate them using `mvn dbflute:freegen`

## Complete Example: Adding Swedish (sv)

```bash
# 1. Navigate to resources directory
cd src/main/resources

# 2. Copy base files
cp fess_label_en.properties fess_label_sv.properties

**Solution**:
- Split large files into smaller batches (e.g., 10,000 docs per file)
- Increase timeout in `system.properties`:
  ```properties
  crawler.document.request.timeout=600000
  ```
- Use asynchronous import via Admin UI instead of API

#### Issue: Special characters in documents not displaying correctly

**Solution**:
- Ensure source files are UTF-8 encoded
- Check `fess_config.properties`:
