A few things you might want to try with Google:

Hand type the following prefixes and note their utility:

link:url Shows other pages with links to that url.

related:url same as "what's related" on serps.

site:domain restricts search results to the given domain.

allinurl: shows only pages with all terms in the url.

inurl: like allinurl, but only for the next query word.

allintitle: shows only results with terms in title.

intitle: similar to allintitle, but only for the next word. "intitle:webmasterworld google" finds only pages with webmasterworld in the title, and google anywhere on the page.

cache:url will show the Google version of the passed url.

info:url will show a page containing links to related searches, backlinks, and pages containing the url. This is the same as typing the url into the search box.

spell: will spell check your query and search for it.

stocks: will lookup the search query in a stock index.

filetype: will restrict searches to that filetype. "-filetype:doc" to remove Microsoft word files.

daterange: is supported in Julian date format only. 2452384 is an example of a Julian date.

maps: If you enter a street address, a link to Yahoo Maps and to MapBlast will be presented.

phone: enter anything that looks like a phone number to have a name and address displayed. Same is true for something that looks like an address (include a name and zip code)

site:www.somesite.net "+www.somesite.+net"
(tells you how many pages of your site are indexed by google)

allintext: searches only within text of pages, but not in the links or page title

allinlinks: searches only within links, not text or title

I hope there is something new in here for you and maybe this infos will be helpfull for ya.
