Media search doesn't include file name

[johnbillion]

Upload a file called foo.png and then do a search for foo.png (either on the Media screen or in the new media modal) and it won't find the file.

Probably existed since forever. Marking as 3.0.

Yes, we've never searched on file name only on attachment post title/post content. Would be a nice enhancement for the media search.

As the file name is used for post title, many users get confused why they cannot find previous media files if they changed the title.

Consider this scenario for support of this change:

1. User uploads a bunch of files to Media Library. One such file is white.png
2. User changes the title of file white.png to Rainbows
3. Months later, user wants to see whether a file on his computer (the same white.png) has already been uploaded to the Media Library
4. Since user has hundreds of files in the Media Library by now, he decides to search for the file by name using "white"
5. User does not find white.png and cannot remember the title that he gave to the image (Rainbows), and so he needs to re-upload the file instead of being able to use the same one again
