I tried a few...
Google desktop never worked for me (too slow and file number limitation) so I won't miss it.
Among the others I tried:
Copernic started crashing on my content
Windows desktop search. No comment.
Exalead that was too slow
etc...
I still use an old version of X1 (last free version).
But I can't understand that there is nothing better widely available.
Biting the hand that feeds IT
