Searchfeedr is a search engine whose vertical is RSS. Unlike your typical search engine, this one tries to make things a tad simpler by combining an interface allowing users to search by source (e.
g. URL of a webpage, feed URL, de.licio.us tag or username) in one box, and cross referencing it with the actual search query in the other box. The ‘Search Over’ filter gives you two options—domains and pages. You can tick certain domains to remove them from the results. Additionally, you can choose from four search engines to supply your queries: Google, Yahoo, Microsoft Live, and Altavista. Bookmark your search queries to your del.icio.us account or with a Firefox bookmark and you’ll be able to pull your feedroll back to your search page. The results are shown within the SearchFeedr screen. You can open up a direct link by clicking on ‘Search URL’. A bookmarklet for posting SearchFeedr to Del.icio.us, wink and Technorati is in the works.

Why SearchFeedr.com It Might Be A Killer
