StrataFS vs. Elasticsearch for semantic code search — when each makes sense
Elasticsearch is the workhorse of full-text search. StrataFS is the new workhorse of embedded semantic search. Here's an honest comparison for developer-focused use cases.

Notes on semantic search, AI agents, and embedded databases.
Long-form writing on hybrid retrieval, MCP, SQLite-as-search-engine, and the architectural choices behind StrataFS.
Claude Desktop + StrataFS: a five-minute MCP setup for your codebase
Wire StrataFS into Claude Desktop in five minutes. Hybrid search across your code and docs becomes a tool Claude knows how to call. Step-by-step, with the config and the troubleshooting.
Index S3, GCS, and Azure Blob buckets with semantic search
Indexing cloud storage used to mean pipelines, copies, and a separate search service. StrataFS reads buckets in place with read-only credentials and exposes a hybrid search across all of them.
Self-hosted semantic search: local AI indexing without SaaS lock-in
Most 'AI search' tools want your data on their servers. We didn't want to send our files anywhere, so we built StrataFS. Here's the case for self-hosted semantic search.
SQLite as a hybrid search engine: FTS5, sqlite-vec, and embedded retrieval
The 'embedded search server' used to be a contradiction. With SQLite FTS5 for BM25 and sqlite-vec for cosine similarity, both indexes live in one file — and one SQL query fuses them.
Hybrid search: combining BM25 and vector ranking in one SQL query
Hybrid search isn't a gimmick — it solves real failure modes of pure BM25 and pure vector retrieval. Here's the math, the SQL, and the tuning knobs that matter.
Building AI agents that understand your knowledge base
The Model Context Protocol is the USB-C of agent integrations — but most MCP servers stop at the protocol. StrataFS goes further: hybrid retrieval, pre-shaped responses, per-source isolation, all local.
Semantic search for your codebase: an alternative to grep
Grep is precise but literal. Semantic code search finds the file you mean, not the file you spelled. Here's why hybrid retrieval beats either alone — and how to run it locally with StrataFS.
Index your storage. Search it like a human.
