Query string with AND operator in nested query not working. Any idea? - elasticsearch

Question

I want to get the document in which nested child contains both words Mifune AND Miller-Meteor.
For more detail of nested, I've gone through https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-nested-query.html
here are the mappings
{
"mappings" : {
"properties" : {
"driver" : {
"type" : "nested",
"properties" : {
"last_name" : {
"type" : "text"
},
"vehicle" : {
"type" : "nested",
"properties" : {
"make" : {
"type" : "text"
},
"model" : {
"type" : "text"
}
}
}
}
}
}
}
}
i've two documents in the index
{
"driver" : {
"last_name" : "McQueen",
"vehicle" : [
{
"make" : "Powell Motors",
"model" : "Canyonero"
},
{
"make" : "Miller-Meteor",
"model" : "Ecto-1"
}
]
}
},{
"driver" : {
"last_name" : "Hudson",
"vehicle" : [
{
"make" : "Mifune",
"model" : "Mach Five"
},
{
"make" : "Miller-Meteor",
"model" : "Ecto-1"
}
]
}
}
query as below
{
"query" : {
"nested" : {
"path" : "driver",
"query" : {
"nested" : {
"path" : "driver.vehicle",
"query" : {
"bool" : {
"must" : [
{ "match" : { "driver.vehicle.make" : "Mifune" } },
{ "match" : { "driver.vehicle.make" : "Miller-Meteor" } }
]
}
}
}
}
}
}
}
I tried the above query but it did not work
also tried with query_string AND operator but it also not worked
{
"query": {
"nested": {
"path": "driver",
"query": {
"nested": {
"path": "driver.vehicle",
"query": {
"bool": {
"must": [
{
"query_string": {
"query": "Mifune AND Miller-Meteor",
"fields": ["driver.vehicle.make"]
}
}
]
}
}
}
}
}
}
}

This is how you should query multiple nested fields.
There are two Nested queries inside your must clause.
The bool->must operator should be outside of your internal nested fields.
GET my_index/_search
{
"query": {
"nested": {
"path": "driver",
"query": {
"bool": {
"must": [
{
"nested": {
"path": "driver.vehicle",
"query": {
"match": {
"driver.vehicle.make": "Mifune"
}
}
}
},
{
"nested": {
"path": "driver.vehicle",
"query": {
"match": {
"driver.vehicle.make": "Miller-Meteor"
}
}
}
}
]
}
}
}
}
}
Results:
"timed_out" : false,
"_shards" : {
"total" : 1,
"successful" : 1,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : {
"value" : 1,
"relation" : "eq"
},
"max_score" : 2.769686,
"hits" : [
{
"_index" : "my_index",
"_type" : "_doc",
"_id" : "2",
"_score" : 2.769686,
"_source" : {
"driver" : {
"last_name" : "Hudson",
"vehicle" : [
{
"make" : "Mifune",
"model" : "Mach Five"
},
{
"make" : "Miller-Meteor",
"model" : "Ecto-1"
}
]
}
}
}
]
}
}
