### 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);
```

#### 2. Add Suggestion Documents

```java

 * It uses a {@link UrlFilterService} to manage the URL filtering rules.
 * The class supports caching of include and exclude patterns for scenarios where a session ID is not available.
 * It also provides methods to initialize the filter with a session ID, clear the filter,
 * match a URL against the defined patterns, and process a URL to add include or exclude patterns based on predefined filtering patterns.
