Search Does Not Return Results For Nested Collections When Parent Collection is Selected

[sharpattack]

Selecting a Collection to limit search results to, does not return results for nested collections' contents.

For example: Selecting "GV Black" collection on /catalog page, then searching for "portrait of g.v. black" will not return results because the "Portrait of G.V. Black" file is in the nested "Series IV. Photographs" collection.
