@dosubot[bot] commented on GitHub (Feb 27, 2025):

Yes, for knowledge base retrieval in Dify, the associated knowledge base is indeed entered through parameters at the start node. Specifically, the sys.query from the start node is used as the query variable to search for relevant text segments within the knowledge base. The knowledge base to be searched must be pre-created within Dify. Additionally, to enable workflow applications to read knowledge base content, you should add a knowledge base retrieval node upstream of the LLM node and fill in the output variable result of the knowledge retrieval node into the context variable of the LLM node [1][2].
