- Check query formatting and filters
- Verify analyzer configurations

**Performance Issues**
- Increase thread pool size in SuggesterBuilder
- Optimize batch sizes for indexing operations
- Review OpenSearch cluster performance

**Memory Usage**
- Configure appropriate JVM heap settings
- Monitor index sizes and optimize mappings
- Use streaming for large data imports

### Debug Logging

```java
// Increase timeout values
client.setConnectionTimeout(60000);  // 60 seconds
client.setSocketTimeout(120000);     // 120 seconds
```

#### Memory Issues
```java
// Reduce concurrent threads and batch sizes
crawler.crawlerContext.setNumOfThread(5);
crawler.crawlerContext.setMaxAccessCount(1000);
```

#### SSL/TLS Issues
```java
// Configure SSL settings
