### 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

        assertTrue(createIndexResponse.isAcknowledged());
    }

    private static void initializeSuggestSettings() throws Exception {
        // Create suggester and get settings
        Suggester suggester = Suggester.builder().build(client, "test");
        settings = suggester.settings();

        // Store analyzer settings
        storeAnalyzerSettings();
    }

                        .numOfNode(1)
                        .pluginTypes("org.codelibs.opensearch.extension.ExtensionPlugin"));
        runner.ensureYellow();
        suggester = Suggester.builder().build(runner.client(), "DefaultContentsParserEdgeCaseTest");
        analyzer = suggester.settings().analyzer().new DefaultContentsAnalyzer();
        defaultReadingConverter = createDefaultReadingConverter();
        defaultNormalizer = createDefaultNormalizer();

        suggester.indexer().index(items);
        suggester.refresh();

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

        SuggestDeleteResponse deleteResponse = suggester.indexer().deleteDocumentWords();

        assertNotNull(deleteResponse);

        final Suggester suggester = Suggester.builder().build(client, "test");

        // Use reflection to access private method
        final Method method = Suggester.class.getDeclaredMethod("getIndicesForAlias", String.class);
        method.setAccessible(true);
        final List<String> indices = (List<String>) method.invoke(suggester, aliasName);

        }

        writer.write(runner.client(), suggester.settings(), suggester.getIndex(), items, false);
        runner.refresh();

        assertEquals(3, suggester.getAllWordsNum());

        SuggestWriterResult result = writer.deleteByQuery(runner.client(), suggester.settings(), suggester.getIndex(),
                QueryBuilders.matchQuery(FieldNames.TEXT, "テスト0"));
