We have seen index-based file searching tools before – but this one is really fast and smart. Once you have your index, results appear in about half a second, then can be narrowed further in realtime. Finder has az optimized reindexing technique which can update your index in a few seconds, and many features for managing your result lists. Can be hidden to system tray, has easy-to-remember keyboard shortcuts for nearly everything, and has a separate reindexer process that can run silently in the background whenever you want it to, disturbing nothing else you work on. (Not even your searches – they can be done paralelly.)

Finder is fairly configurable, has many options and has a relatively small footprint when resident. You just start it, then forget about it – and whenever you need a file, it will be there in a sec.
