> Perhaps I'm under-estimating how computationally heavy search is. It's because they aren't rolling their own search, they pay Google and Bing to do the search for them (via the Google and Bing Search API's which are charged), mix in a few results from their own crawler, and then reorder the results. So they will always have a higher cost base than both Bing and Google, because they are paying for 3 different search indexes (including their own), plus Bing and Google's margins on the API, plus their own infra costs. (Now if this is a sustainable model or not is another question...)
