When using the search feature in my library to search for a string, the search results display each item's original filename that it had when it was first uploaded, instead of the name that I've renamed it to in the library. For example, I have a file that was named "warp field.png" when I uploaded it, and in my library I've renamed it to "Force Field". When I search for "field", it's listed in the search results as "warp field.png" which is the old name. It should be listed as what I renamed it to instead. As a side note, this image is listed in the search results if I search for either "warp" or "force," which is cool. Don't fix that. That's useful. And it makes sense, because renamed items in the library sometimes lose their new name if you delete them out of a folder in your library, but leave them in your recent uploads at the bottom. (Which might be a bug...)
