The mdex-config_MergePolicy attribute in the Global Configuration Record (or GCR) sets the merge policy for the Endeca data store.
You can set the merge policy by sending a request to the Configuration Web Service to change the settings for the GCR, utilizing Integrator or any Web services tool, such as soapUI.
Alternatively, you can use the URL /admin/dstore?op=merge command to change the merge policy of a running data store, or to force a merge.
If you are running a cluster of nodes, you can change the merge policy on the leader node only.
Both of these methods are discussed in the following topics.
