Google is a great search engine, but that doesn't mean you shouldn't try other search engines if you can't find what you're looking for. I know, it's hard to copy the query, go to another site and paste it in the search box.

Try this search on is one of the best Greasemonkey scripts I've ever installed: it's smart enough to detect you're on a search results page (and not only for Google and other big search engines) and shows a small bar at the bottom of the page that includes links to other search engines: Yahoo, Windows Live, Ask and others. This way your query is persistent across most search engines and it's much easier to do research on a topic.

If you don't like the list of available search engines, just edit the code and add other sites. You can also set the value of the checkRef variable to true to show the bar on pages referred from search engines as well.
