An example method for managing datasets produced by alert-triggering search queries may include producing a dataset by executing a search query on a portion of data associated with a time window defined relative to a current time. The method may further include responsive to determining that a portion of the dataset satisfies a condition defining an alert, generating an instance of the alert. The method may further include associating, by a memory data structure, the instance of the alert with an identifier of the query and a parameter specifying a time of execution of the query that has triggered the instance. The method may further include receiving a request for the dataset portion. The method may further include substituting, in a definition of the time window, the current time with the time parameter. The method may further include reproducing the dataset portion by re-executing the query using the time window.
