rustdoc search says “Consider searching for "null" instead.”

[kpreid]

Reproduction Steps

1. Visit https://doc.rust-lang.org/nightly/std/
2. Enter “-> Result<Foo, E>” in the search box.

Output

Type "Foo" not found and used as generic parameter. Consider searching for "null" instead.

The “null” part makes no sense. Probably that sentence should be removed when there is no suggestion.

All we need here is just a null check and a seperate message for when no suggestion is found, fairly straightforward.
