The issue you're encountering is due to a known limitation in Dify's integration with Qdrant. Specifically, Qdrant does not support full-text search for numbers or letters. This limitation is documented in the Dify repository, where it is noted that "milvus/zilliz/relyt doesn't support bm25 search" ^[1].

To address this, you might consider using alternative indexing and retrieval strategies provided by Dify, such as vector search or hybrid search, which may offer better support for your use case. Additionally, you can adjust parameters like TopK and Score Threshold to fine-tune the retrieval process ^[2][3].
