I find time and time again that I’ll do a search in the App Search Tool and it will turn up 0 results, but if I refresh the editor and search again, it will show results.
This seems to especially happen if I haven’t refreshed the editor since yesterday, even if I haven’t made any changes that would impact the things I’m searching for.
The reason this is important is because in the past I’ve done the above search and then deleted things because I thought they weren’t being used, but then later I find out they were being used and it was really just the App Search Tool being a jerk.
Hope that helps someone
