Claim:
1. One or more computer storage media having computer-executable instructions embodied thereon that when executed by a computing device perform a query simplification, the instructions configured to: determine whether a query received at the search interface is a candidate for simplification based on a frequency or rank associated with similar prior queries in a search engine frequency log, the determining comprising: identifying a regression model for a rank distribution for Uniform Resource Identifiers (URIs) corresponding to previous queries in the search engine frequency log; obtaining ranks for URIs for the query; and identifying the query as a candidate for simplification when the ranks for the URIs are lower than an expected rank in view of the regression model for the rank distribution; apply one or more statistical models to the query to generate simplified queries, the one or more statistical models being at least one of machine translation accessing title-query pairs, the title-query pairs corresponding to prior queries matched to titles associated with URIs that are included in search results for the prior queries, maximum entropy, or condition random fields; issue the one or more simplified queries to one or more search engines, obtain search results for the one or more simplified queries from the one or more search engines, merge the search results for the one or more simplified queries, and transmit the merged results to a user for display.
