Hi,
I’m sorry for the late response, somehow I didn’t get a notification about your reply.
I have looked up your configuration, and made a few quick changes, that I think will resolve the issue:
1. I have enabled the index table engine, it is overall better for looking individual keywords: https://i.imgur.com/xEz3RrT.png
2. I have changed the search logic: https://i.imgur.com/5cbkM69.png
This logic will prefer whole word matches first, then random/fuzzy matches
