### Testing

The project uses JUnit 4 with embedded OpenSearch for integration testing:

```bash
# Run all tests
mvn test

# Run specific test class
mvn test -Dtest=SuggesterTest

# Run with verbose output
mvn surefire:test -Dmaven.surefire.debug=true
```

### Running Tests with Coverage

```bash
mvn clean jacoco:prepare-agent test jacoco:report
```
