title: jira curl to get issues
body: <p>I am trying to get data in jira server using curl. I tried this command</p>
  
  <pre><code>    curl -u username:password -X GET -H "Content-Type: application/json" jiraServer/rest/api/2/search?jql=created &gt;= "2015-11-18"
  </code></pre>
  
  <p>It downloaded a file in the curl directory and the file says</p>
  
  <p>{"errorMessages":["Error in the JQL Query: Expecting operator before the end of the query. The valid operators are '=', '!=', '&lt;', '>', '&lt;=', '>=', '~', '!~', 'IN', 'NOT IN', 'IS' and 'IS NOT'."],"errors":{}}</p>
  
  <p>I tried put the created >= "2015-11-18" in advanced search in Jira web interface and it works. Don't why it failed in curl?</p>
