Abstract
Methods, systems, and computer program products for maintaining up-to-date pre-computed search results, such as travel recommendations, stored in a data cache maintained, for example, by a global distribution system. Pre-computed search results are re-computed to provide long-term accuracy. A re-computation controller assigns a re-computation indicator to any of the pre-computed search results. The re-computation indicator for a pre-computed search result is based on at least on a probability that the pre-computed search result is still valid, and on a re-computation frequency of the search result. Within a given time interval, a computation platform re-computes these pre-computed search results having a re-computation indicator indicating the highest need for re-computation. The number of pre-computed search results re-computed by the computation platform is limited by the computation resources of the computation platform that are available for the re-computation within the given time interval.
