Google May Use The Conjoiner Engine to Merge Local Results and Universal Results Together

While presenting the search results before the user, Google may use the conjoiner engine in order to diversify and merge the local and universal search results together. The local search results are returned by local search engine and the universal search results are returned by universal search engine (for web results). Both these engine use separate functions to determine the relevancy and authority of web pages present in their index. A third engine known as the “Conjoiner Engine” merges the results returned by both the local and universal engines and presents them before the user using a different function. Before presenting the final results, a re-ranker engine orders the results as per the authority of the respective web pages.

A patent granted to Google in March 2013 gives a brief explanation about how Google uses the conjoiner and re-ranker engine in order to diversify the search results presented before the user.
