The Knowledge Search by a few Categories action allows your AI assistant to perform focused semantic searches across multiple specified Knowledge Base categories. Unlike the standard Knowledge Search, this action retrieves a set number of documents per category, allowing for broader coverage across relevant topics.

​
🔍 What It Does

This action queries selected categories in your Knowledge Base and retrieves the top-matching documents from each, based on a similarity threshold. It’s useful when your assistant needs a balanced perspective across multiple content segments.
✨ Use this when you want to fetch the most relevant documents from several categories, rather than the overall best matches.
