Make Spotlight search System and hidden files?

[btoth]

I've noticed that Spotlight will not return results when I search for files that are in the System folder (I did a reindex just to make sure), and of course it won't find hidden files (or any Unix files).

Is there a way to make Spotlight index everything?

This might help you achieve that (though I have had no time to test that in practise).
