title: Sorting string column in Kibana visualization
body: <p>I have a <code>status</code> field in my elastic search index which can take values <code>Open,Closed,Clear,Intermediate,Ready for Approval</code>. Right now, I have created a visualization and sorted this field descending based on the Term. What I want to achieve is - I want this to be sorted in this particular order <code>Open,Clear,Intermediate,Ready for Approval,Closed</code>.</p>
  
  <p>How do I achieve this? One option I am thinking is creating a scripted field and prefixing with integer column, but I am not sure if I will be able to filter the visualization later?</p>
