Hi Marilyn,
The issue is not the visible part, I know what you mean on the screenshot.
The actual database does not have those stored, but as I pointed out in the screenshot, the module on the bottom of the screen has those keywords. Those are data attributes to an element within a HTML tag, and that is only visible in the page source. Nevertheless that is part of the database content field as text and therefore it matches the query.
If you want to test, you can remove the search bar from any of those pages, and they will still appear in the results as before.
If you try the suggested configuration, it will further process the database and will only search the visible content:
- Using the index table engine
- And the following keyword logic without exact matches
I strongly suggest this configuration, it will resolve your issue.
