title: How can I search GitHub pull requests?
body: <p>I'm currently viewing a popular GitHub repo. Inside there are over 300 pull requests (100 open, 200 closed).</p>
  
  <p>How can I search these pull requests to see if a particular topic already exists within them?</p>
  
  <p>i.e. I don't want to create some code and submit a pull request if someone has already done a similar pull.</p>
  
  <hr>
  
  <p>Edit: Alternatively - since I know what file(s) I plan on changing - is it possible to view a specific file on GitHub, and say "Hey. Are there any outstanding pull requests that relate to this specific file?".</p>
  
  <hr>
  
  <p>Update: GitHub now offers this easily - when browsing a repository the search bar at the top offers to search only the select repo - which makes it much easier to search for what you need.</p>
