rustdoc: Search returns weird and unhelpful results

[camelid]

I found this while searching for Vec::sort:

This is an issue on nightly, beta, and stable.

(I just created a label for rustdoc's search feature, A-rustdoc-search, to help categorize issues related to the search bar. Hope that's okay!)

This is because Vec has no sort method, only [T] does.

Being able to search for methods from derefs using the pointer type's name does seem like a reasonable feature to have, though.
