“search by text” doesnt recognize meta or attributes

hello,

while setting up a “search by text” filter, I noticed a couple of things:

• the only thing the filter seems to search for is product categories
• I cant figure out how to make it search for custom site meta, although I’ve successfully set up an “attribute” filter to filter by the same meta
• the search filter doesnt include any “attributes” content in its searches either, even though I have successfully set up another Attribute filter.

Not sure if I’m completely missing something, but I couldnt seem to find anything in the documentation either.

thanks!
