Often the displayed cluster name is based on a variant of the cluster which is not popular or even useless. Example @hede: A cluster is called "vausschnitt Pullover" and the MQ is "pullover v ausschnitt". "vausschnitt" has 0 popularity within this cluster but is the main title of the cluster. 2 optimizations would be helpful: rename the cluster after the master query (no matter if set manually or data based) option to rename a cluster (overwriting the existing clustername)
