I would suggest that “Search everything” also search content from Monday docs.
I was trying to create an activity dashboard with certain notes to be added.
It would be imperative that the search could track those notes in an easy-to-read text format.
We found that Monday docs would suite are needs, until we realized that search everything does not actually search everything, including the content of Monday docs 
There’s another longer thread on this topic. Search also doesn’t search mirrored columns, which is extremely inconvenient.
