title: how to specify URL in filters pagePath core reporting api V3
body: <p>I am building a web app that pulls data through the Core Reporting Api v3 from Google. I am using the client PHP library offered by Google. 
  I am currently trying to specify a page and retrieve its pageviews for a time range. Every other seems to be working okay except for the fact that if a specfy a filter with <code>ga:pagePath==http://link/uri</code> then I get <code>0</code> all the time no matter the time range. </p>
  
  <p>I think the problem is got to do with the setting of value for this pagePath. I want to have spearate data for the desktop version of the site and the smartphone version <code>denoted by s. subdomain</code></p>
  
  <p>Can anyone hint me on some tips and or tricks to use to get the required data?</p>
  
  <p>Example URL:
      <a href="http://domain.com/user/profile/id/1" rel="noreferrer">http://domain.com/user/profile/id/1</a>
      <a href="http://s.domain.com/user/profile/id/1" rel="noreferrer">http://s.domain.com/user/profile/id/1</a></p>
  
  <p>Thanks in advance!</p>
