coze知识库检索出来的数据为什么会凭空少很多？

我手动去coze的milvus数据库检索数据，用同样的输入，同样的Embedding，同一个milvus数据库，为什么coze工作流检索回来的少很多

coze检索出来的结果，每次都只有1-2个：

手动检索的结果：

Reproduce the Coze workflow retrieval and the manual Milvus query using the same input, embedding, and database described in the issue. Compare their result counts and inspect the retrieval settings or filtering involved; done means identifying why the workflow returns only one or two results and documenting a reproducible fix or explanation.
