Hi FIT W., Thanks for your response. And yes, I did test with exact keywords, and I tried with file upload, and also with Google drive file, none of these worked on my knowledge base search node. I tried multiple basic queries, since the file uploaded is very simple, it only has about 10 facts, nothing else. If you are referring to search fuzziness to set manually, I tried that and also auto. Is there a chance I am missing a step in my WF? or a setting not properly defined for the source data? Thanks
