Validate activity before betting a new project on cherche. - Data & Retrieval: Skip a heavy ingestion framework when your corpus is small and static; a script plus the embedding API is enough. - Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers. - Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate. ## When NOT to use langchain_semantic_search - Seeking a solution that supports large-scale, real-time or non-Google Drive document collections - Require a fully integrated end-to-end service without configuration for drive paths ## Common questions ### What is the difference between cherche and langchain_semantic_search? cherche: Neural Search. langchain_semantic_search: Semantic search for Google Drive files using GPT3, LangChain, and Python.
