If your Jive-x environment is configured to allow OpenSearch to be consumed by your jive-n environment, then users would see the public content that would be searchable as a guest user in your Jive-x.
Here is an example of my test site that I have bridged to the Jive Community and performed a search. The documents returned to me are the same had I searched the community as a guest:
Hope this helps.
Based on your response it sounds like there are two requirements to make Bridging useful:
- OpenSearch enabled and configured
- Guest access enabled and configured
Is that accurate? Thanks!
