Semantic Search Backends Embedding Tools

Tools and microservices that implement vector-based semantic search infrastructure using embeddings, similarity scoring, and retrieval systems. Includes Spring Boot services, search engine integrations (Elasticsearch, Solr, FAISS), and hybrid search implementations. Does NOT include embedding models themselves, general full-text search without semantic capabilities, or high-level search UI applications.

There are 17 semantic search backends tools tracked. The highest-rated is openviglet/turing at 45/100 with 67 stars.
