13. The method of claim 10 , wherein outputting the reranked promoted results and the search results further comprises outputting data corresponding to a link for content associated with the promoted results.
10. A computer-implemented method for dynamically reranking search results based upon source authority, the computer-implemented method comprising performing computer-implemented operations for: analyzing a received search query to determine a query topic associated with the search query; performing a search on an authority index utilizing the search query and generating search results to identify authoritative sources relating to the query topic, the authority index comprising a plurality of entries, wherein each entry defines an authoritative source for content relating to the query topic, wherein identifying the authoritative sources comprises, accessing the authority index comprising a plurality of entries, each entry defining an authoritative source that created for content relating to a plurality of query topics, searching the authority index to identify authoritative sources for content related to the query topic, each authoritative source associated with a promoted result relating to the query topic, identifying a plurality of entries associated with the query topic, each of the plurality of entries being associated with a source have a corresponding authority value and corresponding to one of the promoted results, and defining the authoritative sources as the sources that authored the promoted results; obtaining the promoted results in response to the searching; computing at least one contribution dimension for the sources associated with the promoted results; generating a contribution dimension filter for filtering the promoted results and the search result based upon the contribution dimension; and dynamically reranking the promoted results and the search result based upon the contribution dimension in response to receiving input indicating a command to apply the contribution dimension filter to the promoted results and the search result; and outputting the reranked promoted results with the search result.
