You can also use standard relational operators to compare string values. However, filters that use standard relational operators to compare string values will not be saved with the trigger subscription on Broker. If the subscription filter resides only on Integration Server, Broker automatically places the document in the subscriber’s queue. Broker does not evaluate the filter for the document. Broker routes all of documents to the subscriber, creating greater network traffic between Broker and Integration Server and requiring more processing by Integration Server.
