### Basic Usage

#### 1. Create Suggester Instance

```java
import org.codelibs.fess.suggest.Suggester;
import org.opensearch.client.Client;

// Initialize with your OpenSearch client
String suggestId = "my-suggest-index";
Suggester suggester = Suggester.builder().build(client, suggestId);
```

import org.codelibs.fess.suggest.exception.SuggestSettingsException;
import org.codelibs.fess.suggest.index.SuggestDeleteResponse;
import org.codelibs.fess.suggest.index.contents.document.ESSourceReader;
import org.codelibs.fess.suggest.settings.SuggestSettings;

        assertEquals(2, suggester.getDocumentWordsNum());
        assertEquals(1, suggester.getQueryWordsNum());

        suggester.indexer().deleteDocumentWords();
        suggester.refresh();
        assertEquals(1, suggester.getAllWordsNum());
        assertEquals(0, suggester.getDocumentWordsNum());
        assertEquals(1, suggester.getQueryWordsNum());
    }

    @Test

        assertTrue(createIndexResponse.isAcknowledged());
    }

        settings = suggester.settings();

        // Store analyzer settings
        storeAnalyzerSettings();
