### OpenSearch Integration

```java
// Add OpenSearch dependency and configure
container.singleton("opensearchDataService", OpenSearchDataService.class, service -> {
    service.setIndexName("crawler-data");
    service.setHostname("localhost");
    service.setPort(9200);
});
```

## Performance Tuning

### Thread Configuration

```java
// Optimize thread pool settings

    @Test
    public void test_setNullIndexName() throws Exception {
        SuggestIndexer indexer = suggester.indexer();
        // Setting null index name should be allowed (though may cause issues later)
        indexer.setIndexName(null);
    }

    @Test
    public void test_setNullSupportedFields() throws Exception {
        SuggestIndexer indexer = suggester.indexer();
        // Setting null fields should be allowed

        assertTrue(remainingWordsCount > 0);
    }

    @Test
    public void test_setters() throws Exception {
        SuggestIndexer indexer = suggester.indexer();

        assertNotNull(indexer.setIndexName("test-index"));
        assertNotNull(indexer.setSupportedFields(new String[] { "field1", "field2" }));
        assertNotNull(indexer.setTagFieldNames(new String[] { "tag1", "tag2" }));
