influence content based on domain
Fragment of a discussion from Project:Support desk
You could use multiple wikis and enable Manual:$wgEnableScaryTranscluding to transclude pages from other wikis.
So you would have a master wiki and sub-wikis. The master wiki contains all of the content. The sub-wikis would have articles but the content of these articles would just transclude from the master wiki. Would the sub-wikis still index themselves? What is, if you search a sub-wiki for text that is in a master wiki article, will the sub-wiki return results?
