1. A diagnostic system that facilitates evaluation of performance of a search system, comprising: a memory for storing a plurality of components comprising executable program code; and a processor functionally coupled to the memory, the processor being responsive to computer-executable instructions contained in the program code and operative: to identify a set of substantially similar search queries issued by a plurality of search system users, wherein the set of substantially similar search queries are grouped for analysis, the grouped set of search queries being issued by disparate search system users; to identify a mapping recommendation that relates the grouped set of search queries issued by the disparate search system users to an accepted asset within a data collection when at least one query in the set of search queries appears in a session that leads to the accepted asset, wherein the at least one query is within a session comprising a plurality of queries, the at least one query comprising at least one previous query made prior to a subsequent query, the subsequent query resulting in the retrieval of an accepted asset in the session, wherein the at least one previous query does nor result in the retrieval of the accepted asset, wherein the mapping indicates a relationship between the grouped set of search queries and the accepted asset where the grouped set of search queries would not otherwise be associated with the accepted asset; to evaluate search system performance as a function of the set of search queries; and to generate a confidence value based upon the amount of support for the mapping within the search data that reflects probable user satisfaction associated with the mapping recommendation, wherein the mapping recommendation is categorized based upon the confidence value, wherein the mapping recommendation is implemented automatically by the search system when the mapping recommendation has a high confidence value, wherein the mapping recommendation is included in recommendations to content providers by the search system when the mapping recommendation has a mid-range confidence value and wherein the mapping recommendation is identified for further evaluation by the search system when the mapping recommendation has a relatively low confidence value.
