Actions a_kb_search

Knowledge Search

Embeds the query and retrieves top-K chunks from a knowledge base.

What does it do?

Searches for the answer to a customer's question in the Knowledge Base (documents, catalogs or URLs you uploaded to Daguito).

How does it work?

Converts the question into mathematical vectors and searches for the most relevant text fragments in the database. Then extracts the matches for the AI Agent to read.

Why use it?

Prevents hallucinations. Without this node, the bot could invent product prices or features. With it, the bot only answers based on your official information.
