# Cluster

The number of one or more clusters to use to generate a taxonomy. You must specify the cluster job for the clusters by using the SourceJobName parameter. IDOL Server uses the cluster title as the name of the taxonomy.

Separate multiple clusters with spaces, plus symbols (+) or commas. There must be no space before or after a plus symbol or comma. If you specify more than one cluster, IDOL Server generates one taxonomy for each cluster.

NOTE: The numbering of clusters starts from `0` (that is, the first cluster always has the number `0`). To find the number of the cluster, you can use the ClusterResults action to view the clusters in the cluster data specified by SourceJobName.
