Simpler logic for serving results from diverse domains. [launch codename "hc1", project codename "Other Ranking Components"] We have algorithms to help return a diverse set of domains when relevant to the user query. This change simplifies the logic behind those algorithms.
I'm increasingly seeing less domain diversity. Just now, page one consisted of six results from the same domain, three more on page two. Can't be right.
