 "summary": "Install pymilvus with Milvus Lite and create a collection in a local file, no server needed.",
 "who": "A developer prototyping RAG in a notebook who does not want to run a database server yet.",
 "problem": "Setting up a database server just to try vector search slows down early experiments.",
 "outcome": "A working vector collection persisted to a local .db file that you can later move to a server.",
 "steps": [
  "Install the SDK with `pip install -U pymilvus`, and pymilvus[milvus-lite] for Milvus Lite",
  "Create a local database with `MilvusClient(\"milvus_demo.db\")`",
  "Create a collection with `client.create_collection` using your embedding dimension, for example 768",
  "Insert your embedded data with `client.insert`",
  "Search with `client.search`, setting limit and output_fields"
 ],
 "agent_prompt": "Using milvus-io/milvus with Milvus Lite, create milvus_demo.db, embed <documents> with <model>, create a collection with the right dimension, insert them, and search for <query>. Show me the top 3 results with their text.",
