### 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";

        this.stopWords =
                Analysis.parseWords(env, settings, "stopwords", JapaneseAnalyzer.getDefaultStopSet(), NAMED_STOP_WORDS, ignoreCase);
    }

    @Override
    public TokenStream create(TokenStream tokenStream) {
        if (removeTrailing) {
            return new StopFilter(tokenStream, stopWords);
        } else {
            return new SuggestStopFilter(tokenStream, stopWords);
        }
    }
