How can Alpha pull search results from other sites?
Alpha can display any combination of OpenSearch results, RSS or site specific search results on the one page. Alpha does this by utilising the OpenSearch format to read and present search results from any site that chooses to syndicate their results. Much like the way MyYahoo! can read news feeds via RSS, Alpha can read search results via OpenSearch RSS, GeoRSS, standard RSS plus additional sources via the Yahoo! Search API.
