### 3. Update Configuration File

Edit `src/main/resources/fess_config.properties`:

Find the `supported.languages` property (around line 202) and ensure your language code is included:

```properties

    protected String asEsIndex() {
        if (indexName == null) {
            final String name = ComponentUtil.getFessConfig().getIndexConfigIndex();
            indexName = super.asEsIndex().replaceFirst(Pattern.quote("fess_config"), name);
        }
        return indexName;
    }

    protected String asEsIndex() {
        if (indexName == null) {
            final String name = ComponentUtil.getFessConfig().getIndexConfigIndex();
            indexName = super.asEsIndex().replaceFirst(Pattern.quote("fess_config"), name);
        }
        return indexName;
    }

    protected String asEsIndex() {
        if (indexName == null) {
            final String name = ComponentUtil.getFessConfig().getIndexConfigIndex();
            indexName = super.asEsIndex().replaceFirst(Pattern.quote("fess_config"), name);
        }
        return indexName;
    }

    protected String asEsIndex() {
        if (indexName == null) {
            final String name = ComponentUtil.getFessConfig().getIndexConfigIndex();
            indexName = super.asEsIndex().replaceFirst(Pattern.quote("fess_config"), name);
        }
        return indexName;
    }
