Abstract
In one embodiment, a method includes receiving a search query and identifying one or more n-grams. The method also includes accessing, for each identified n-gram, a time-based distribution that includes a count of actions associated with the n-gram. The actions may have occurred within several time windows, and the time-based distribution may count the actions within each time window. The method may also include determining one or more extrema time windows. The method may also include modifying the search query based on the determined extrema time windows. The method also includes executing the modified search query, ranking identified content objects, and sending search results to a client system. The search results may be displayed in ranked order based on the rankings of the corresponding content objects.
