Launch Aspire (if it's not already running). See:
To add a Publish to CloudSearch drag from the Publish to CloudSearch rule from the Workflow Library and drop to the Workflow Tree where you want to add it. This will automatically open the Publish to CloudSearch window for the configuration of the publisher.
In the Publish to CloudSearch window, specify the connection information to publish to the Amazon CloudSearch.
Once you've clicked on the Add button, it will take a moment for Aspire to download all of the necessary components (the Jar files) from the Maven repository and load them into Aspire. Once that's done, the publisher will appear in the Workflow Tree.
For details on using the Workflow section, please refer to Workflow introduction.
