Searching in the app explorer is very nice, but misses the flexible search like the Go To (Ctrl-G) functionality has. It would be great if I can search with spaces because I don't remember the exact name (as one word or seperated by underscores).
Especially when you're looking for usages of Enumerations, constants and JSON snippets, you first need to find the exact name via Ctrl-G and then look it up in the app explorer to find usages.
I would keep the search field for the name, not the document types. If you give your JSON structures the prefix JSON, you can find them in that way.
If you want to find all JSON structures you can use Ctrl-Shift-F:
or simly just allow finding JSON structures when you search for "JSON" in the app explorer instead of just finding files that contain the name
