Lifehacker ran an interesting article yesterday on Mastering Google Desktop Search. There were some gems in the including: Google Desktop advanced search operators

Many of Google’s regular advanced search operators will work for your desktop files, but there are Google Desktop-specific advanced search operators, too. Here are a few that I use on a regular basis:

• under:: Small but powerful, this operator is. The "under:" operator puts a limit on which file folder your results can come from. So, this query: grandpa under:"C:\1_Common Folder\Wendy\Pictures" would only grab pictures titled "grandpa" in my Pictures folder.
• Email search: With thousands of emails floating around on my machine, I especially am grateful for Google Desktop implementing such a powerful way to search emails. There are five separate email search operators: Subject:, To:, From:, Cc:, and Bcc:. Here’s a sample query: subject:merger to:bill gates from:steve jobs. This would grab every email from Bill to Steve with the word "merger" in the subject line.
• the combo platter: You can experiment with combinations on all of these search operators; for example, "chocolate chip" -cookies to:Mom, or filetype:doc under:"C:\Documents and Settings\Wendy\Desktop\movies".

I recommend the whole article.
