Problem

The current Qdrant node in n8n lacks full expression support, specifically in the ‘Get Many’ operation’s “Search Filters” field8. Users can’t use dynamic values or n8n expressions {{}} to create contextualized queries87. This limits the node’s flexibility and requires complex workarounds using Code nodes or direct HTTP requests to the Qdrant API71.

Proposed Solution

Enable expression support for the Qdrant node’s “Search Filters” field in the ‘Get Many’ operation. This would allow users to create dynamic and context-aware queries using n8n expressions, enhancing the node’s functionality and streamlining workflows74.

Benefits

  • Increased Flexibility: Users can create dynamic queries based on data from previous nodes in the workflow1.
  • Simplified Workflows: Reduces the need for complex workarounds using Code nodes, making workflows cleaner and easier to maintain15.
  • Improved Integration: Enables deeper integration with other n8n nodes and services1.
  • Enhanced RAG Applications: Facilitates the creation of more sophisticated Retrieval-Augmented Generation (RAG) pipelines4.

Technical Considerations

The implementation would involve:

  • Extending the Qdrant node’s configuration to support expressions in the “Search Filters” field8.
  • Utilizing n8n’s existing expression evaluation mechanisms to resolve expressions at runtime8.
  • Ensuring proper validation and error handling for dynamic queries.

This enhancement would significantly improve the usability and power of the Qdrant node within n8n, enabling users to build more complex and intelligent automation workflows12.

I hope this is helpful.
