title: Elasticsearch Filtering woes, uppercase vs lowercase field filtering
body: <p>I have a field in my index called &quot;status&quot; of keyword type.</p>
  <p>When I try to filter with {&quot;term&quot;: {&quot;status&quot;: &quot;Publish&quot;}}, it returns no hits
  When I try to filter with {&quot;term&quot;: {&quot;status&quot;: 'publish&quot;}}, it returns the correct result.</p>
  <p>This would be one thing if the status was input as lowercase, but they're actually uppercase.</p>
  <p>My kibana GET returns the products with &quot;status&quot;: &quot;Publish&quot;.</p>
  <p>I also remember inserting the statuses with uppercase values. So why can I only filter by lowercase?</p>
  <p>The big caveat, and I know its suspicious to do this, is I attempted to add the &quot;status&quot; mapping after the item indices were already created. Thats the main culprit for me right now as to why this is happening.</p>
  <p>Does anyone know why the filtering only works with lowercase values when the actual value in the mapping is uppercase?</p>
