Knowledge Base Search Merge

What It Does

Merges search results from multiple Knowledge Bases into a single output, re-ranks them using RRF (Reciprocal Rank Fusion), and supports max token filtering.

Usage

The AI Chat node can only accept one Knowledge Base reference input. If you call multiple Knowledge Bases, you cannot directly reference all of them (as shown below).

Use Knowledge Base Search Merge to combine results from multiple Knowledge Bases into one.

Example Use Cases

1. After question classification, search different Knowledge Bases per category, then feed the merged results to a single AI Chat node. This avoids adding a separate AI Chat node to each branch.
