Spotlight does indeed do this so Mac users don't need this. Might help Windows and Linux users though. I use voidtools.com's Everything tool to search for filenames quickly on Windows as it uses the NTFS index to do near-instant searches, since the Windows Indexing Service has been poor since XP... This might help if you are looking for content instead of just filenames.
