I think it’s fine to return results with とりあい for 取り合い, とにかく for 兎に角, or はずかしめ and 恥ずかしめ for 辱め. I know some might want the exact search result returned, but that is a compromise I think that is better for learning purposes.
I’m not responsible for the userscript. For the game gengo textbook, in the “extra examples” section, some items use regular search, some exact search, and some are hand-picked from the database. That is a better approach.
Edit: I archived the old repo and added the link to the latest one.
