Topic on Talk:Cross-wiki Search Result Improvements

I have two wikis, and I hope the search results are interconnected, like wikipedia ( File:Sidebar-crosswiki-search-results.jpg )，Sister site search results are displayed on the right, what should I do?

Hi, I looked at the linked image and its /ja page: have you had a look at Cross-wiki Search Result Improvements , where everything seems to start/evolve? Pardon me if I am too short-sighted. Cheers,

I've seen it, but the documentation doesn't tell me how to enable it on other wikis.
