1. A method for re-computing pre-computed search results, the method comprising: assigning a re-computation indicator, by a re-computation controller, to each pre-computed search result based at least partially based on a probability that the pre-computed search result is still valid prior to re-computation and a re-computation frequency of the pre-compute search result; and re-computing, by a computation platform, the pre-computed search results for which the re-computation indicator indicates a highest need for re-computation, wherein a number of pre-computed search results that is re-computed is limited by the computation resources of the computation platform available for the re-computation within a given time interval.
