Let's say we are storing objects of type vehicle which have a reference to
a type owner in the following structure. Then Running the following request:
`POST: localhost:9200/15/vehicles/_search'
with the following body:
{ "query": { "wildcard": {"make":"*toy*"} }}
returns the relevant objects:
"took": 5,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
},
"hits": {
"total": 1,
"max_score": 1,
"hits": [
{
"_index": "15.index",
"_type": "vehicle",
"_id": "352",
"_score": 1,
"_source": {
"id": "352",
"name": "toyota",
"owner_id": "12",
"owner": {
"id": "12",
"name": "John Smith",
"login_id": 1,
"active": true,
}
}
}
]
}
I am now attempting to query by nested object (e.g. all vehicles that
belong to user John Smith)
{"query": {"wildcard": {"owner.name": "*John*"}}}
returns no results, while:
{"query": {"wildcard": {"owner": {"name": "*John*"}}}}
errors out with:
"error": "SearchPhaseExecutionException[Failed to execute phase
[query], all shards failed; shardFailures {....
[4]: SearchParseException[....

What is the correct format for a query (wildcard or otherwise) against a
nested object? How specifically do wildcard queries differ from that
template (if at all)?
