  142. <h2>Search Tricks</h2>
  143. <p>
  144. Prefix searches with a type followed by a colon (e.g.
  145. <code>fn:</code>) to restrict the search to a given type.
  146. </p>
  147. <p>
  148. Accepted types are: <code>fn</code>, <code>mod</code>,
  149. <code>struct</code>, <code>enum</code>,
  150. <code>trait</code>, <code>type</code>, <code>macro</code>,
  151. and <code>const</code>.
  152. </p>
  153. <p>
  154. Search functions by type signature (e.g.
  155. <code>vec -> usize</code> or <code>* -> vec</code>)
