Advanced Search Filtering

via “metadata filtering with boolean and range queries”

Self-learning vector database for Node.js — hybrid search, Graph RAG, FlashAttention-3, HNSW, 50+ attention mechanisms

Unique: Integrates metadata filtering directly into vector search without requiring separate database queries, whereas most vector DBs require post-processing or external filtering

vs others: More efficient than filtering results in application code because filtering happens in-process; simpler than maintaining separate metadata in PostgreSQL or MongoDB
