Windows 7 search is actually not all that bad once you learn some key words.
Windows 7 search uses Advanced Query Syntax
(more options described here)
It sounds like you want to do some very basic search functions. Here are some examples.
The following searches for files larger than 8 MB with a name containing the text "filename", having the extension .mp3 and having been modified on the 25th.
name:~~"filename" size:>8 MB ext:.mp3 datemodified:7/25/2011
The double tilde searches for any part in the search string containing your search term. It is like doing a search for "*someSearch*" using the wildcards below. If you don't use the double tilde, it will only search the beginning of words.
For example, doing a search for
name:"ness" when the filename is
"Aewsomeness Somefile.txt" would not show up unless you had the double tilde since those search terms are not at the beginning of words.
You can also use wild-cards like in the good old days (the single tilde lets you use the older style wildcards (? and *):
The "?" is a place holder for any one character. The "*" is a place holder for any number of any characters.
