The ability to search these sites directly is also built in to most browsers. No need to send your query through any search engine. Firefox setup: - Go to the page with the search you want, e.g. wikipedia.com - Right-click the search box - "Add a Keyword for this search" - Type your "keyword" e.g. w Now any time you want to search wikipedia, go to the URL bar and type w plus a space first, then your search term. Chrome setup: I haven't used Chrome for a while but it also has this feature. You add "keywords" for your site searches somewhere in the settings instead of via right-clicking the search box, but the usage once it's set up is the same.
