Abstract: In an example, in connection with a search clustering system, a grouping component retrieves a timestamp set of news queries and determines a time-stable set of news query groups by performing the first stage of a two-stage clustering technique. A clustering component determines a time-stable set of news query groups clusters by performing the second stage of the two-stage clustering technique. The performance of the two-stage clustering technique is aided by a least recently used caching component. The time-stable set of news query groups clusters may be served to a web page in order to generate a trending topic list for display.
