Issue
Search facets are randomly returned empty or zeros.

Cause
Elasticsearch logs:
CircuitBreakingException[[fielddata] Data too large, data for [_id] would be [12986458957/12gb], which is larger than the limit of [12879672115/11.9gb]]

Resolution
Increase indices.breaker.fielddata.limit setting

curl -X PUT localhost:9200/_cluster/settings -H 'Content-Type: application/json'  -d '{
    "persistent" : {
      "indices.breaker.fielddata.limit" : "80%" 
    }
  }'
