For found tags, find document name. Send cross tags and document names. Destroy session for user’s search session cookie.

What’s next? Write documentation and make the repository public Make the use of authenticated sets optional Implement the database generating algorithm for other platforms Single-machine process? Other distributed data processing techniques? Move inter-process communication away from Java serialization
