System and Method for Query Re-Issue in Search Engines

Abstract

A system embodiment receives a query from the user. The query is processed by a search infrastructure which may return a set of results. Results may then be estimated for quality by a quality estimator. The quality estimator may determine an initial quality estimation of the search result(s). A query re-issuer generates re-issued query information based on the initial quality estimation of the search result(s) for the initial query. A query modifier then receives the re-issued query information and generates a modified re-issued query in accordance with the query re-issue information. A method embodiment modifies and re-issues a query to the search infrastructure. The method includes determining an initial quality estimation of the search result, generating re-issued query information based on at least an initial quality estimation of the search result for the initial query, receiving the re-issued query information and generating a modified re-issued query.

1 . (canceled) 
     
     
         2 . A computer-implemented method comprising:
 receiving, by a query reviser and from a query re-issuer, (i) re-issued query information indicating that an initial search query generated search results that were automatically identified as unacceptable, and (ii) an instruction to modify the initial search query for resubmission to a search engine;   in response to receiving the instruction from the query re-issuer to modify the search query for resubmission to the search engine, generating, by the query reviser, a modified search query for resubmission to the search engine; and   submitting, by the query reviser, the modified search query to the search engine.   
     
     
         3 . The method of  claim 2 , wherein the re-issued query information indicates that the initial search query generated search results that were automatically identified, by the query re-issuer, as unacceptable before the search results were output at a user device. 
     
     
         4 . The method of  claim 2 , wherein the query reviser receives the instruction from the query re-issuer in lieu of the query re-issuer transmitting a subset of set of search results for output at a user device. 
     
     
         5 . The method of  claim 2 , comprising receiving, by the query reviser and from the query re-issuer, data indicating a number of times that the user search query has been re-issued. 
     
     
         6 . The method of  claim 2 , wherein the re-issued query information indicates a number of queries that are waiting to be re-issued by the query re-issuer. 
     
     
         7 . The method of  claim 2 , wherein the re-issued query information indicates a representation of the estimate of quality of the set of search results. 
     
     
         8 . The method of  claim 2 , wherein the re-issued query information indicating that the initial search query generated the search results that were automatically identified as unacceptable is generated based at least on an estimate of quality of the search results. 
     
     
         9 . A system comprising:
 one or more computers; and   a non-transitory computer-readable medium coupled to the one or more computers having instructions stored thereon which, when executed by the one or more computers, cause the one or more computers to perform operations comprising:
 receiving, by a query reviser and from a query re-issuer, (i) re-issued query information indicating that an initial search query generated search results that were automatically identified as unacceptable, and (ii) an instruction to modify the initial search query for resubmission to a search engine; 
 in response to receiving the instruction from the query re-issuer to modify the search query for resubmission to the search engine, generating, by the query reviser, a modified search query for resubmission to the search engine; and 
 submitting, by the query reviser, the modified search query to the search engine. 
   
     
     
         10 . The system of  claim 9 , wherein the re-issued query information indicates that the initial search query generated search results that were automatically identified, by the query re-issuer, as unacceptable before the search results were output at a user device. 
     
     
         11 . The system of  claim 9 , wherein the query reviser receives the instruction from the query re-issuer in lieu of the query re-issuer transmitting a subset of set of search results for output at a user device. 
     
     
         12 . The system of  claim 9 , comprising receiving, by the query reviser and from the query re-issuer, data indicating a number of times that the user search query has been re-issued. 
     
     
         13 . The system of  claim 9 , wherein the re-issued query information indicates a number of queries that are waiting to be re-issued by the query re-issuer. 
     
     
         14 . The system of  claim 9 , wherein the re-issued query information indicates a representation of the estimate of quality of the set of search results. 
     
     
         15 . The system of  claim 9 , wherein the re-issued query information indicating that the initial search query generated the search results that were automatically identified as unacceptable is generated based at least on an estimate of quality of the search results. 
     
     
         16 . A non-transitory computer storage device encoded with a computer program, the program comprising instructions that when executed by one or more computers cause the one or more computers to perform operations comprising:
 receiving, by a query reviser and from a query re-issuer, (i) re-issued query information indicating that an initial search query generated search results that were automatically identified as unacceptable, and (ii) an instruction to modify the initial search query for resubmission to a search engine;   in response to receiving the instruction from the query re-issuer to modify the search query for resubmission to the search engine, generating, by the query reviser, a modified search query for resubmission to the search engine; and   submitting, by the query reviser, the modified search query to the search engine.   
     
     
         17 . The device of  claim 16 , wherein the re-issued query information indicates that the initial search query generated search results that were automatically identified, by the query re-issuer, as unacceptable before the search results were output at a user device. 
     
     
         18 . The device of  claim 16 , wherein the query reviser receives the instruction from the query re-issuer in lieu of the query re-issuer transmitting a subset of set of search results for output at a user device. 
     
     
         19 . The device of  claim 16 , comprising receiving, by the query reviser and from the query re-issuer, data indicating a number of times that the user search query has been re-issued. 
     
     
         20 . The device of  claim 16 , wherein the re-issued query information indicates a number of queries that are waiting to be re-issued by the query re-issuer. 
     
     
         21 . The device of  claim 16 , wherein the re-issued query information indicating that the initial search query generated search results were automatically identified as unacceptable is based at least on an estimate of quality of the search results.
