More Information on Architecture an Features

Hello,

is there somewhat more information on the architecture and the features of Argo available?

The interesting questions for me are

- Is Argo a search engine or just a meta search framework?

- How can 3rd party search engines be connected?

- Where can I search? Back end, Desktop, Exchange, etc.

- How is the Integration into the NW portal?

Thanks for any information.
