Hello @heoyongun! I'm Dosu, a friendly bot here to help you with bugs, answer your questions, and assist you in becoming a contributor. I'm ready to dive into your issue while we wait for a human maintainer. Let's tackle this together!

The issue you're experiencing with the Economical Indexing mode in Dify, where non-English keywords are not returning search results, might be related to limitations in language support for this specific indexing mode. Economical Indexing uses an Inverted Index, which is optimized for keyword retrieval but may not handle non-English languages effectively due to differences in language structure and encoding [1][2][3].

To address this, you might consider switching to a different indexing mode that supports multilingual search more robustly, such as Hybrid Search, which combines full-text and vector search capabilities. This mode allows for cross-language semantic transformations and can be customized with settings like TopK and Score Threshold to improve search accuracy across different languages [4][5][6].

If switching modes is not feasible, you may need to check if there are any specific configurations or updates available for your version (1.4.0) that enhance language support in Economical Indexing.

@dosubot[bot] commented on GitHub (May 19, 2025):

I apologize for the confusion. The Economical Indexing mode in Dify uses an inverted index structure, which is optimized for quick keyword retrieval but does not inherently support cross-language semantic search. This mode is more suitable for scenarios where users know the exact terms they are searching for. However, specific limitations regarding non-English language support in Economical Indexing are not explicitly documented in the sources I have access to [1][2].
