It's an Iterator that uses an attached Parser to read the text value you write/paste in its Config parameter (labeled 'Raw Text Data'). If you furthermore drop this Iterator into a Connector Loop, then you can map in the Connector Parameters you want, and then instruct the Loop to re-initialize and issue the search query, or just re-issue another query (no re-init).
So you map the Attribute value you want to parse as the assignment of the entryRawData parameter, attach your Parser, set up the Input Map and you're in business.
This Connector is standard issue with TDI 7.
