## Troubleshooting

### Common Issues

**Index Creation Fails**
- Verify OpenSearch cluster is accessible
- Check index permissions and mappings
- Ensure sufficient cluster resources

**Suggestions Not Appearing**
- Confirm documents are indexed: `suggester.refresh()`
- Check query formatting and filters
- Verify analyzer configurations

**Performance Issues**
