Allow users to exclude folders


I have a project that has many files at the root level that I need included in the search. But in the root I also have several folders that have TONS of files that are 3rd party.

Like this:
                 + 3rdPartyFolder-+
                  |                          Tons of Files here that I don't ever need to search
                 + corefile.cs
                 + anotherCoreFile.js
                 + Index.html
My only options now are to include all the 3rdPartyFolder files or to not include corefile.cs, anotherCoreFile.cs and Index.html.

If i could add MyProject, but then exclude a list of folders under that (3rdPartyFolder) it would make this more useful.
