Add the dependency to your `pom.xml`:

```xml
<dependency>
    <groupId>org.codelibs.fess</groupId>
    <artifactId>fess-suggest</artifactId>
    <version>15.2.0-SNAPSHOT</version>
</dependency>
```

### Basic Usage

#### 1. Create Suggester Instance

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

// Initialize with your OpenSearch client
