[OKD] Search on docs.okd.io seems broken for 4.17

[mstoebich]

It seems like the search functionality is broken on docs.okd.io, but only for release 4.17. It works fine for both "latest" and 4.16. No matter what search term is provided, it will always return "No results found. Try rewording your search."

I have already tried clearing the cache and trying it through Private Mode on Firefox. I also get the same behaviour on Edge.
