Searching by filename and location?

Hello. Would be possible to add to the Search filter items like Location and/or Filename? I've got many music files sorted in folders with names "Artist - Album" and tracks with names with only "Title.mp3" without artist's name. And with no tags inside. So it is imported in my collection, i can see it, but it's not included in search results, so I'm not able to find these files in my collection. I know, maybe it's a lot of programming. But Virtual DJ can do it without no problems, so why Rekordbox shouldnt do it? Thank you for your response. :-)
