Brain Memory Hybrid Search
Bir agent'in memory/bilgi korpusu icin BM25 (lexical) + pgvector (semantic) hibrit arama, RRF skor birlesimi…
A complete recipe for a hybrid memory-search endpoint that combines BM25 lexical search with pgvector semantic search and fuses them with Reciprocal Rank Fusion, returning a diverse top-5. It recalls thousands of accumulated notes through one RAG endpoint with a sub-200ms P95 target, and injects results into agent context. Where exact term match wins it uses BM25, where intent matters it uses vectors, and the fusion beats either alone.

Every recall query fires two searches at once, lexical and semantic, then fuses the results. What follows is the full pipeline from chunking and masking to the five diverse chunks that land in agent context under 200ms.
- Chunks each memory file into 512-token windows with 64-token overlap, masks personal data and secrets before any embedding API call, and tags every chunk with its source file and cluster
- Embeds chunks in batches of 64 and upserts them into Postgres with an embedding version label, alongside an auto-generated full-text index on the same rows
- At query time, runs keyword search (BM25 over the text index) and vector search (HNSW cosine) in parallel, each returning its top 100 ranked candidates
- Fuses the two lists with Reciprocal Rank Fusion (k=60), a rank-based merge that needs no score normalization, so a document strong in either modality rises
- Applies a diversity filter before returning: maximum 2 chunks per source file plus a per-cluster quota, so one old note cannot dominate the injected context
- Returns the top 5 chunks into the agent context, bumps their recall counters asynchronously, and logs latency against the 200ms budget; chunks recalled too often get flagged for staleness review

-
Do I need a dedicated vector database, or will Postgres carry this?
Postgres carries it: pgvector handles the semantic side and tsvector the lexical side, so on Supabase or plain Postgres there's no separate vector store to run. The whole hybrid endpoint lives in one database.
-
If semantic search already understands meaning, why bother with BM25 lexical on top?
Because semantic search fumbles exact tokens: IDs, names, error codes, while lexical search misses paraphrases. Reciprocal Rank Fusion blends both rankings so you don't lose precise matches or conceptual ones; that combination is the whole point.
-
Does the sub-200ms target hold once my notes reach the millions?
That P95 target is framed around thousands of notes, not millions. At much larger scale you move into index tuning territory, this is a solid starting architecture, not a promise that latency stays flat forever.
