IF you want to do a craigslist search (and not use SearchTempest), the following works great:

go to google and enter the search
xx xx site:craigslist.org

where xx are the search words you want to use. Thus, if you want to search for a Deuce roadster, go to google and search for:

deuce roadster site:craigslist.org

and you will get every ad in the entire USA that has these two words
