                 <p>
                     Prefix searches with a type followed by a colon (e.g.
                     <code>fn:</code>) to restrict the search to a given type.
                 </p>

                 <p>
                     Accepted types are: <code>fn</code>, <code>mod</code>,
                     <code>struct</code>, <code>enum</code>,
                     <code>trait</code>, <code>type</code>, <code>macro</code>,
                     and <code>const</code>.
                 </p>

                 <p>
                     Search functions by type signature (e.g.
                     <code>vec -> usize</code> or <code>* -> vec</code>)
                 </p>
