title: Instagram API - Search for user in Sandbox mode
body: <p>I have difficulty using the <code>/users/search</code> endpoint according to the documentation in the Instagram magnificent API. I have Sandbox app set up, I have sandbox users added, I have a valid <code>access_token</code>, but when searching, Instagram returns an empty array of data with the <code>200 code</code>. Yes, I am sure the users I look for are there. </p>
  
  <p>Has anybody experienced something like this in the past? Last time I've used that feature was about two months ago, and it worked fine. </p>
  
  <p>Could it be some transient glitch, or am I missing something? </p>
