Filtering Documents across a Cluster Gateway
A filter string specifies criteria for the contents of a document. Broker uses the filter string to determine which documents match your requirements and allows only those documents to pass through the cluster gateway.
You apply filter strings to those document types that a cluster gateway can receive from a remote cluster.
To set a filter on a document type
1. In My webMethods: Messaging > Broker Clusters > Cluster Gateways.
2. In the Cluster Gateway List, locate the cluster gateway that you want to configure and click 
Details. 3. Click the Shared Document Types tab.
4. In the list of the document types that the cluster gateway is permitted to forward, click 
Edit Filter for the document type that you want to filter. 5. In the Filter text box, type a filter string that specifies the criteria that identifies which documents this gateway can forward to the remote cluster. For information about specifying a filter string, see
Filtering Documents. 6. Click Apply.
The filter appears in the Filter column in the Allow Forward table.
