Use this parameter to specify a two-character identifier for the clustering strategy. Use a different identifier for each clustering strategy that searches the same identity table. However, if you want to maintain the initial clusters that you create, use the same identifier for the Best or Merge method.

For example, use the Pre-clustered method to create initial clusters with

AA

as the identifier. To maintain the clusters, use the Best or Merge method with

AA

as the identifier because the Best or Merge method must operate on the same clusters that the Pre-clustered method creates.
