SearchEngineFilter.com lets you specify specific sites that you would like to include or exclude from your search results. If you enter sites to include, only results from those sites will be returned in your search. If you enter sites to exclude, the search will drop those sites from the search results. Currently the search only works on Google. Other search engines will be added at a future date, as well as the ability to save your Favorites to a database. Currently the Favorites will persist
