## Troubleshooting

### Common Issues

#### Connection Timeouts
```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);

/**
 * Monitor target for tracking hot threads in the OpenSearch cluster.
 * This class extends MonitorTarget to provide monitoring functionality for
 * hot threads, which helps identify performance bottlenecks and resource
 * usage issues in the search engine cluster.

    private static final Logger logger = LogManager.getLogger(HotThreadMonitorTarget.class);

 * It writes data to a temporary file once the data size exceeds a specified threshold.
 *
 * <p>This class ensures that the temporary file is deleted if it is not needed.
 * It uses a logger to log warnings if there are issues deleting the temporary file.</p>
 *
 * <p>Fields:</p>
 * <ul>
 *   <li>{@code logger} - Logger instance for logging warnings.</li>
 *   <li>{@code PREFIX} - Prefix for the temporary file name.</li>

 * It also provides a method to retrieve the extracted data as a String from an AccessResultData object.

 * The class handles character encoding issues by attempting to use the specified charset.
 * If the specified charset is invalid, it falls back to UTF-8.

        writeLittleEndianInt(baos, 10); // size
        writeLittleEndianLong(baos, 25); // Unaligned offset (not multiple of 8)

## Troubleshooting

### Common Issues

**Index Creation Fails**
- Verify OpenSearch cluster is accessible
- Check index permissions and mappings
- Ensure sufficient cluster resources

**Suggestions Not Appearing**
- Confirm documents are indexed: `suggester.refresh()`
- Check query formatting and filters
- Verify analyzer configurations

**Performance Issues**
- Increase thread pool size in SuggesterBuilder
