## 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

    @Override
    public boolean isFetchNarrowingEffective() {
        return getSqlClause().isFetchNarrowingEffective();
    }

    @Override
    public void xdisableFetchNarrowing() {
        // no need to disable in ConditionBean, basically for OutsideSql
        String msg = "This method is unsupported on ConditionBean!";
        throw new UnsupportedOperationException(msg);
    }
