  - Advanced filtering with tag, text, numeric, and geo field support
  - Hybrid queries combining vector search with metadata filters
  - Batch operations with configurable batch sizes
  - Pagination support for large result sets
  - TTL/expiration support for time-based data
  - Connection pooling and cluster support via Jedis
  - Comprehensive test suite with 233 passing tests
  - Integration with LangChain4J for embeddings
