How Google Ranks Desktop Search Results

Bill has found three related patents regarding Google Desktop Search. It’s very interesting to look under the hood and see what the algo is doing, and speculate if there are any similarities on the web engine.

The first one describes a ranking algorithm which shows results based not only on relevance to a search, but also frequency of use – on the assumption that documents and information that are viewed frequently tend to be what someone will be looking for….The second discusses how the search is an incremental one, in that as you begin typing a query, it provides results….The third talks about having two separate indexable databases – one for titles alone, and another for the full text of documents/objects – and how both of these indexes are searched and results from them are merged together
