title: lunr: Return the stem of the searched terms so I can highlight it within results
body: <p>I'm using lunr to perform a search and I currently am highlighting the search from the value of the search text area, but lunr uses a stemmer and returns results that don't specifically match the full search term.  is there a way to access the stem of the search term that lunr ends up searching on?</p>
  
  <pre><code>// query our lunr index
  searchResults = _.map(index.search($('#searchInput').val()), function (res) {
      var uid = res.ref;
      return mediaList[uid];
  });
  </code></pre>
