### 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

        // Then
        assertSame(originalBuffer, reusedBuffer, "Released buffer should be reused");
    }

     * Simple test implementation of BufferCache for testing purposes

    private static class TestBufferCacheImpl implements BufferCache {
        private final List<byte[]> cache;
        private final int bufferSize;
        private final int maxBuffers;

 * {@code readBytesWireFormat}.
