Fastest search app?

Hi,

I came from using Windows and am looking for a Mac alternative to a program called "Everything" (http://www.voidtools.com/).

I like Spotlight and Finder, but it doesn't find all the files (hidden folders or certain filetypes it seems, like when I was searching for an .ini file in an external drive's hidden app folder).

Right now I am using EasyFind but it's slow compared to Everything and it seems to search on-the-fly instead of using an index. I think I tried a similar program but they both are slow compared to Everything.

Is there an app that finds every single file and folder "instantly" just like Everything on Windows?

Thanks
