For instance, sorting on a field that has null values for some documents, without specifying the value to use as a replacement, will result in a non-error HTTP status code, with search results, but the returned JSON will contain a non-empty "_shards.failures" array.

Example:

 
                                                                {
  "took" : 5,
  "timed_out" : false,
  "_shards" : {
    "total" : 3,
    "successful" : 1,
    "failed" : 2,
    "failures" : [ {
      "shard" : 0,
      "index" : "guests",
      "node" : "BmJBXb6JRDm89f6ljEA9HA",
      "reason" : {
        "type" : "search_parse_exception",
        "reason" : "No mapping found for [uniqueNumericField] in order to sort on"
      }
    } ]
  },
  ...
}
 
                                                            

We should report such failures, be it only in a debug log. Maybe we should even throw an exception?
