Language reference search not working?

I have started using 2017r1 and I can’t get the top level search to do anything. I open the language reference and type something in the search field in the toolbar, hit return, and I get nothing. Is it broken, or is something wrong with my installation? I’m using OS X Sierra.

which means you’re using the online references (correct ?)

There is a search field on each page that should work as well
