Make notes field searchable?

Testing out AudioFinder and planning on putting notes on thousands of clips. But it seems that the search bar won’t search for any of the content I put in the notes field. Is there a way to make it do this?

If not, any recs for other software?
(bonus-- software that can help me automate the copying and pasting of all that note info IN? I have audio clips and txt files w matching names – need to reconnect them in this, or another, database.)
