1. A method for adaptively processing a query search, the method comprising:
- probabilistically expanding the query to sub-queries;
retrieving sub-query results;
merging the sub-query results into a search result;
adapting the search such that the relevance of the search result is increased when the search is repeated; and
storing the search result in tangible computer readable memory; and
wherein expanding the query to sub-queries includes assigning a confidence level to the at least one of the sub-queries, wherein the confidence level is based on a probability of relevance.

Abstract
A method, system and computer program for adaptively processing a query search. An expanding operation is utilized to expand the query into sub-queries, wherein at least one of the sub-queries is expanded probabilistically. A retrieving operation retrieves the results of the sub-queries, and a merging operation is used to merge the sub-query results into a search result. An adapting operation is configured to modify the search such that the relevance of the search result is increased when the search is repeated.
