I'm already using Confluence as my KB for Customer Success, with loads of troubleshooting articles.
I'm considering moving my documentation over to Confluence as well. For obvious reasons of cost, the way I'd like to implement it is with two Confluence instances: One stripped down with the minimum of add-ons for Customer Success, one souped up with the maximum of add-ons for Documentation.
But I can't do this if there's no way to search in one place within both instances. Any ideas how this can be affected?
