SearchCloud Weights Keywords To Improve Search Relevance

SearchCloud, a new search engine that launched on July 17, has a new take on search refinement that it hopes will make it a useful alternative to the likes of Yahoo and Google. Instead of simply entering multiple keywords, users can rank how important each term is to the search. Each term is placed in a “search cloud”, where its weight is indicated by the size of the font. For example, you could enter the words “TechCrunch” and “Apple” with TechCrunch more strongly weighted to (hopefully) get articles about Apple on our site. To further refine the search, you could enter terms like “iphone” and “app store” with a lesser weighting, which would help stories on those topics rise to the top, without excluding stories that don’t mention them.
