I have been acquainted with win xp and after installing win 7, I find one component in win xp which I have not found in win 7, or I am not just quite familiar with the latter.

The "search" option in win xp, where one can search files or folders and even word/s in a document....however, the search box in win 7 is not that helpful, or again it might just be me, not a techie...

Can anyone help me on how to search files/folders or just by mere word in a document using the search box of win 7?

Are there software which could perform similar "search" like that of win xp?
