title: How to get issues from a project that have status "in progress" using Redmine REST API
body: <p>I am trying to get specific issues from a plan.io project using the Redmine REST API. I want to list issues from a project that have the status of "in progress" or "to estimate". But I am not sure what kind of query string to write. I cant find any thing in API documentation on the redmine site.</p>
  
  <p>Here is how to get all the issues from a project.</p>
  
  <pre><code>http://someurl.com/issues.json?key=185f14564g65f4g65df4g46570a0eb4267&amp;project_id=2
  </code></pre>
  
  <p>But how do I get only the issues from a project that have status equal to "in progress" or "resolved" etc. I know how to get IDs for the statuses but not sure how write the query. This is what I tried but didnt work.</p>
