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 200 , with search results, *but* the returned JSON will contain a non-empty "_shards.failures" array.
Example:
{code}
{
"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"
}
} ]
},
...
}
{code}
We should report such failures, be it only in a debug log. Maybe we should even throw an exception? |
