title: WebStorm cannot find usages of a exported function
body: <p>I have a js file name business_video.js containing some functions. At the end I export them:</p>
  
  <pre><code>  module.exports = {
          checkShare,
          checkDownloadFile,
          uploadVideo,
          quickTransferVideo,
          searchVideoInshared,
          renameVideo,
          deleteVideo,
          addTags,
          deleteTag,
          downloadFileToFromHDFSToServer,
          doesFileExistInServer,
          videoSquare,
          getVideoInfoByIdsArray
      }
  </code></pre>
  
  <p>I want to find a function name <code>getVideoInfoByIdsArray</code>'s usage in the whole project, including those who use <code>const  abc = require('../business_video')</code> then <code>abc.getVideoInfoByIdsArray()</code>. </p>
  
  <p>However I when I press F7 on 
  <code>function getVideoInfoByIdsArray(){...}</code> it show the only usage is in the <code>module.exports={...}</code>. How can I find the usages in the whole project? </p>
