Anybody know something that can help to index selected hard drives for affordable time and affordable summary index space that I could search over all selected drive by keyphrase etc. I want something similar to search engine - only local version. Desktop engine...

Any suggestions?

Don't suggest Google desktop search - I tried and don't like it.

Here is a link to reviews of the top Desktop Search Apps:

And fyi, Google recently did some revamping on theirs:

I hope this helps!
