title: how to search a particular word or entry inside a sub folder in a repository on github
body: <p>I am just looking for an example ( the correct command to fire in the advance search at github ) about  searching a word <strong>inside a folder</strong> of a particular repository. I guess this will involve the "path:" option but not sure how to use it <br /></p>
  
  <p>As an example I need to search for a function name "clean" or a test case for "clean" or similar function inside the jquery test suite at the following location - <br />
  <a href="https://github.com/jquery/jquery/tree/master/test" rel="noreferrer">https://github.com/jquery/jquery/tree/master/test</a> <br /></p>
  
  <p>I understand there are some filters like repo: and path: provided by github but not sure how to use them. </p>
  
  <p>Also I am not satisfied with an answer posted for a similar question at - 
  <a href="https://stackoverflow.com/questions/9401923/search-a-github-repository-for-the-file-defining-a-given-function">Search a github repository for the file defining a given function</a></p>
  
  <p>I understand I can fork it to my local machine and do a search there but I  don't want to download the whole repository simply to search it. I just need to search it online at the github site itself.</p>
  
  <p>Thanks in advance !!</p>
