title: Jira JQL query how can I get the all issues that include any of multiple labels
body: <p>I currently have a Jira soap webservice that allows users to get a list of issues by label.
  I have a new requirement to allow multiple labels (only return items that include 1 or more of the labels in the set <code>(test1,test2)</code>).</p>
  <p>The Label search requires the IN command. Below is what I currently have:</p>
  <pre><code>query = string.Format(&quot;status = {0} AND project = {1} AND Label In({2})&quot;,
  status,project,formattedLabel);
  </code></pre>
  <p>I can't seem to find any documentation on jira query syntax.</p>
  <p>How do I modify this query to return only issues that include all the lables passed by the user?</p>
