Google desktop search:  It seems a terrible concept to have your drive indexed on someone else's server (despite all the good people in the world).

Copernic has always been a dog, but that is what I still use until I can replace it with a complete solution.

Everything and neoSearch are new contenders (speed and low impact on resources), but I don't think they search within files (yet?).

Stopka can search direct or build an index, and it searches within files.  The author said it doesn't index email. (don't know if it searches it?)

To search within files is crucial!  There is no perfect file naming system.

Searching email is crucial!  How could it not be?  Further, everyone does not use Outlook.  It is only text, regardless which email program, so lets figure out how to search it.

 Everything, neoSearch, and Stopka seem to be approaching the "Holy Grail" in this space (still not there).  Why has so much R&D on searching the entire ethersphere failed miserably at enabling one to search a finite hard drive for something already "known"?
