  110. <h2>Search Tricks</h2>
  111. <p>
  112. Prefix searches with a type followed by a colon (e.g.
  113. <code>fn:</code>) to restrict the search to a given type.
  114. </p>
  115. <p>
  116. Accepted types are: <code>fn</code>, <code>mod</code>,
  117. <code>struct</code>, <code>enum</code>,
  118. <code>trait</code>, <code>type</code>, <code>macro</code>,
  119. and <code>const</code>.
  120. </p>
  121. <p>
  122. Search functions by type signature (e.g.
  123. <code>vec -> usize</code> or <code>* -> vec</code>)
