Include folder tree in search results
The names of folders in the directory tree should be included in search results. It is strange, that when searching for a term that appears in the name of a folder, one can get a "no results" page.
My suggestion would be to (either/both) highlight the matching directories in the tree, the same way as it is the case when you hit ALT on one of the items; or to include them in the list of search results.
On my Mac, for example, when searching for e.g. "Informatics" using spotlight, I do get a list of matching folders. It totally makes sense to me.
Maybe the reason why you think that "it wouldnt make sense to display the collection itself" is because you conceive search in Zotero more as "filtering of items" instead of a "search for stuff" use case?
