```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);
```

#### 2. Add Suggestion Documents

```java
import org.codelibs.fess.suggest.entity.SuggestItem;
