  119. <h2>Search Tricks</h2>
  120. <p>
  121. Prefix searches with a type followed by a colon (e.g.
  122. <code>fn:</code>) to restrict the search to a given type.
  123. </p>
  124. <p>
  125. Accepted types are: <code>fn</code>, <code>mod</code>,
  126. <code>struct</code>, <code>enum</code>,
  127. <code>trait</code>, <code>type</code>, <code>macro</code>,
  128. and <code>const</code>.
  129. </p>
  130. <p>
  131. Search functions by type signature (e.g.
  132. <code>vec -> usize</code> or <code>* -> vec</code>)
