Issue with multi_match queries for nested documents

Elastic Stack Elasticsearch
1

I need multilanguage text search for documents and decided to use types and
multi_match queries for that as described in http://www.elastic.co/guide/en/elasticsearch/guide/current/mapping.html

It works smoothly for flat documents, but I cannot figure out whether it is
applicable to nested documents too.
Here is a test index "persons"

{
"settings" : {
"number_of_shards" : 2
},
"mappings" : {
"person_eng":{
"properties": {
"name" : {
"type" : "string", "analyzer" : "english"
},
"car":{
"properties": {
"make": {
"type": "string", "analyzer" : "english"
},
"model": {
"type": "string", "analyzer" : "english"
}
},
"type" : "nested"
}
}
},
"person_de":{
"properties": {
"name" : {
"type" : "string", "analyzer" : "german"
},
"car":{
"properties": {
"make": {
"type": "string", "analyzer" : "german"
},
"model": {
"type": "string", "analyzer" : "german"
}
},
"type" : "nested"
}
}
}

}

}

After putting documents

curl -XPUT 'http://localhost:9200/persons/person_eng/1' -d '{
"name" : "Bob Mahoney",
"car" :
{
"make" : "Vickers Armstrongs",
"model" : "Matilda"
}
}'

curl -XPUT 'http://localhost:9200/persons/person_de/1' -d '{
"name" : "Heinz Guderian",
"car" :
{
"make" : "Porsche",
"model" : "Tiger"
}
}'

the following query works as expected

{
"query": {
"multi_match": {
"query": "Heinz",
"fields": [
"person_de.name",
"person_eng.name"
]
}
}
}

but a nested query doesn't return any result

{
"query": {
"nested": {
"path": "car",
"query": {
"multi_match": {
"query": "Heinz",
"fields": [
"person_de.car.make",
"person_eng.car.make"
]
}
}
}
}
}

What is wrong here?

If fully qualified field name (including type name) is not supported in
multi_match query for nested documents, I quess it can be replaced by
corresponding
dis_max or boolean query.

Thanks in advance!
