  <h2 class="_lined-heading" id="search">Search</h2>
  <p>
    The search is case-insensitive and supports fuzzy matching (for queries longer than two characters).
    For example, searching <code class="_label">bgcp</code> brings up <code class="_label">background-clip</code>.<br>
    Abbreviations are also supported (<a href="#abbreviations">full list</a> below).
    For example, <code class="_label">$</code> is an alias for <code class="_label">jQuery</code>.
  <dl>
    <dt id="doc_search">Searching a single documentation
    <dd>
      You can scope the search to a single documentation by typing its name (or an abbreviation),
      and pressing <code class="_label">Tab</code> (<code class="_label">Space</code> on mobile devices).
      For example, to search the JavaScript documentation, enter <code class="_label">javascript</code>
      or <code class="_label">js</code>, then <code class="_label">Tab</code>.<br>
      To clear the current scope, empty the search field and hit <code class="_label">Backspace</code>.
    <dt id="url_search">Prefilling the search field
    <dd>
      The search field can be prefilled from the URL by visiting <a href="/#q=keyword" target="_top">devdocs.io/#q=keyword</a>.
      Characters after <code class="_label">#q=</code> will be used as search string.<br>
      To search a single documentation, add its name and a space before the keyword:
      <a href="/#q=js%20date" target="_top">devdocs.io/#q=js date</a>.
    <dt id="browser_search">Searching using the address bar
    <dd>
      DevDocs supports OpenSearch, meaning it can easily be installed as a search engine on most web browsers.
      <ul>
        <li>On Chrome, the setup is done automatically. Simply press <code class="_label">Tab</code> when devdocs.io is autocompleted
            in the omnibox (to set a custom keyword, click <em>Manage search engines\u2026</em> in Chrome's settings).
        <li>On Firefox, open the search engine list (icon in the search bar) and select <em>Add "DevDocs Search"</em>.
            DevDocs is now available in the search bar. You can also search from the location bar by following
            <a href="https://support.mozilla.org/en-US/kb/how-search-from-address-bar">these instructions</a>.
