Remove directories from file searching

If I am searching for the file Class.cs that is in a directory called Class, I'll get both results to show up in the file search window. I would like some way to make file searching not show directories in the search. I don't remember this being much of an issue with 2017.1, it seems to provide directories as search results (and makes them the top result) more often.

Note, this is not to hide the contents of Class from file searching, just the actual directory itself.
