Keyword search ## Find the exact phrase, fast. Classic full-text search over every indexed document chunk, powered by Postgres's native full-text search — no separate search index to keep in sync. - Postgres full-text search over indexed chunks - Works the moment a document finishes processing - In development — targeted for the next build milestone Semantic search ## Find the right idea, even with the wrong words. Documents are embedded into 768-dimension vectors and compared by meaning, not just matching text — so a question about 'remote work expenses' can surface a passage that says 'home-office reimbursement' instead. - 768-dim embeddings via Cloudflare Workers AI (BGE base) - Stored and queried with pgvector - In development Hybrid search ## The best of both, blended automatically. A reciprocal-rank-fusion blend of keyword and semantic results, so an exact match and a conceptual match both surface without you having to pick a mode. - Reciprocal rank fusion (RRF) of keyword + semantic result sets - One query, one ranked list - In development [Previous Features: all 3 pages](https://royalsoftworks.com/products/queryllama/features/) [Next Answers, your model, and five roles.](https://royalsoftworks.com/products/queryllama/features/answers-and-roles/) [All of QueryLlama features](https://royalsoftworks.com/products/queryllama/features/)
