The Telligent webpage says
Telligent Community uses a rating service to allow people to like and/or rate content, as well as a commenting service to enable more detailed feedback. These services are not necessarily tied to user generated content types (e.g., blog posts, forum threads, etc.) only and may be extended to be used on external content, such as a product page hosted on a separate content management system.
Telligent Community supports Open Search and can be integrated with other search platforms already in use.
We have a potential use case where we would want to use Telligent search to return search results from a separate website (in our case a documentation website). Not sure if it is relevant but neither the Telligent community or documentation site are public so Google is not going to index it.
Has anyone accomplished this or something similar and if so may be able to share details? Thanks for any help.
