RE-COMPUTING PRE-COMPUTED SEARCH RESULTS

摘要

Pre-computed search results are re-computed by a computation platform based on available computing resources. A search platform maintains at least a first and a second group of pre-computed search results and provides the first group of pre-computed search results at a first provision time and the second group of pre-computed search results at a second provision time to requesting clients. A re-computation controller schedules the re-computation of the pre-computed search results on the basis of validity probabilities being associated with the pre-computed search results and the respective provision times. Re-computation of the first group and the second group is scheduled such that the validity of the search results of the first group given by the validity probabilities is maximized at the first provision time and the validity of the pre-computed search results of the second group given by the validity probabilities is maximized at the second provision time.
