I don't think so. I just went to their site and the first case study i opened was from theguardian.com. I went to theguardian.com and went to do a search. Guess who they are using to power their search function? Google.

In my opinion which means nothing, sites need to figure out how to power their own search. Using a third party isn't going to work for most. Maybe people need to focus on building custom architecture that indexes the data in a more structured way rather than cobbling systems together that ultimately hinder search efforts when its time to get the user what they want. I don't know the answer but somebody eventually will. Maybe wordpress will create a powerful search for all those wordpress sites.
