Methods, systems, and computer program products for re-computing pre-computed search results, such as pre-computed priced recommendations. Pre-computed search results stored in a search platform are subdivided into shares of related pre-computed search results including a first share. A re-computation controller determines a validity trend indicating a change rate of a validity probability of a pre-computed search result over time and an instantaneous validity rate for the pre-computed search results. If a difference between the instantaneous validity rate and the validity trend exceeds a given extent, the re-computation controller adjusts the validity probabilities being associated with other pre-computed search results included in a second share correlated with the first share. The re-computation controller issues re-computation orders to a computation platform to re-compute a part of the pre-computed search results, the part being selected by the re-computation controller on the basis of the validity probabilities associated with the pre-computed search results.
