Why the search of the RuboCop docs website is so terrible?

[repoles]

First of all, I really love RuboCop. But I have to say: the search of the RuboCop docs website is horrible! It just doesn't work! It didn't used to be like this. For example, I'm in the main page. I hit ⌘K to open the search and type "Style/ClassAndModuleChildren". The search displays many results, none of them is what I'm looking for. OK, so I try to type just "ClassAndModuleChildren". No results! I'm missing something? Why the search does't find the direct link to Style/ClassAndModuleChildren documentation?
