## Development Commands

### Setup
```bash
mvn antrun:run          # Download OpenSearch plugins (required before first build)

- Don't call `refresh()` too frequently
- Limit `maxReadingNum` to prevent memory issues
- OpenSearch auto-refreshes every 1 second by default

### Compatibility
- Designed for OpenSearch 2.x+
- All text processing uses UTF-8
