                Prefix searches with a type followed by a colon (e.g.
                fn:) to restrict the search to a given type.
            
                Accepted types are: fn, mod,
                struct, enum,
                trait, typedef (or
                tdef).
            
                Search functions by type signature (e.g.
                vec -> usize)
