15. An apparatus comprising: a processor; and memory storing computer executable instructions that, when executed by the processor, perform a method of clustering, comprising: determining a first set of clusters to display from a plurality of search query results, each of the plurality of search query results being associated with at least one cluster in the first set of clusters; determining a title to display of at least one cluster in the first set of clusters; after determining the title to display of the at least one cluster in the first set of clusters, identifying an input indication to recluster the plurality of search query results; determining a second set of clusters to display, which excludes one or more clusters from the first set of clusters, each of the plurality of search query results being associated with at least one cluster in the second set of clusters.

An apparatus according to claim 15 , wherein the method of clustering further comprises: determining a title to display of at least one cluster in the second set of clusters, wherein identifying an input indication, determining the second set of clusters, and determining the title to display of a least one cluster in the second set of cluster are continuously repeated as a loop.
