## Optional: Search Analysis Support

If your language requires special text analysis (stemming, stop words, etc.), you may need to configure OpenSearch analyzers.

### 1. Update OpenSearch Index Template

Edit `src/main/resources/fess_indices/fess.json` to add language-specific analyzers.

**Example for Swedish:**
```json
