SMART CACHE FOR TRAVEL SEARCH COMPUTER SYSTEM HOSTING A TRAVEL META-SEARCH ENGINE

A computer-implemented method to retrieve results for a travel search task executed on a computer system hosting a travel meta-search engine comprises obtaining a travel search task specifying one or more values of each search task parameter of a set travel search task parameters, obtaining search task normalization information for the search task, normalizing the search task, wherein normalizing the search task includes adapting at least one search parameter of the search task based on the search task normalization information, determining a cache key corresponding to the normalized travel search task, determining if a cache of the computer system hosting a travel meta-search engine includes a search result for the normalized search task, the cache including search results of previous travel search tasks indexed by a cache key and if the cache includes a search result for the normalized search task, retrieving the search result from the cache.
