# NumClusters

The maximum number of clusters that IDOL Server must identify or return in this action.

NOTE: For the ClusterSnapshot action, the number of sample documents that IDOL Server uses to create a snapshot is based on this value.

If you set `NumClusters` to `0`, IDOL Server uses the default value.
