This article advocates for a "local first" approach to developing retrieval-augmented generation (RAG) systems, emphasizing the importance of starting with retrieval rather than complex infrastructure. The author suggests using a small set of real-world documents and user-generated questions to test retrieval effectiveness, highlighting that lexical matching is crucial for specific queries like product codes or names, while semantic search excels with broader context. The piece also touches on the benefits of hybrid retrieval and proposes using simpler local databases like SQLite with FTS5 for early-stage development before scaling to production-ready systems like PostgreSQL with pgvector.
