Knowledge Retrieval Node

The Knowledge Retrieval Node queries your knowledge bases to find relevant information for AI-powered responses.

Overview#

Use Knowledge Retrieval Nodes to:

• Implement RAG (Retrieval Augmented Generation)
• Search documentation or FAQs
• Find relevant context for LLM responses

Configuration#

Knowledge Base#

Select which knowledge base to query.

Query#

The search query, typically using variables:

{{input.user_question}}

Top K#

Number of relevant results to retrieve (default: 5).

Similarity Threshold#

Minimum similarity score for results (0.0 - 1.0).

Output#

Returns an array of matching documents with:

• content - The document text
• score - Similarity score
• metadata - Document metadata

Using with AI Nodes#

Combine with AI Nodes for RAG:

1. Knowledge Retrieval finds relevant context
2. AI Node uses context to generate informed responses
