elasticsearch match on every element in the nested collection - elasticsearch

Question

I am trying to perform an elastic-search query that will return documents where "every" element of the nested collection has a match, not just one.
For example, I have a Driver object, with the List of cars, and each car has the color attribute.
Driver index:
curl --location --request PUT 'localhost:9200/driver' \
--header 'Content-Type: application/json' \
--data-raw '{
"mappings": {
"properties": {
"driver": {
"type": "nested",
"properties": {
"name": {
"type": "text"
},
"car": {
"type": "nested",
"properties": {
"color": {
"type": "text"
}
}
}
}
}
}
}
}'
And the following data: Driver John with green and red car, and Driver Bob with two green cars.
curl --location --request PUT 'localhost:9200/driver/_doc/1' \
--header 'Content-Type: application/json' \
--data-raw '{
"driver": {
"name": "John",
"car": [
{
"color": "red"
},
{
"color": "green"
}
]
}
}'
curl --location --request PUT 'localhost:9200/driver/_doc/2' \
--header 'Content-Type: text/plain' \
--data-raw '{
"driver": {
"name": "Bob",
"car": [
{
"color": "green"
},
{
"color": "green"
}
]
}
}'
I want to find the driver that has ONLY green cars (i.e. Bob).
I tried the following query, but it returns a driver that has at least one car that matches color:
curl --location --request GET 'localhost:9200/driver/_search' \
--header 'Content-Type: application/json' \
--data-raw '{
"query": {
"nested": {
"path": "driver",
"query": {
"nested": {
"path": "driver.car",
"query": {
"bool": {
"must": [
{
"match": {
"driver.car.color": "green"
}
}
]
}
}
}
}
}
}
}'
This query returns every driver that has at least one green car. What is the fix? Thank you.

You can add a must_not query explicitly ruling out red:
{
"query": {
"bool": {
"must": [
{
"nested": {
"path": "driver.car",
"query": {
"match": {
"driver.car.color": "green"
}
}
}
}
],
"must_not": [
{
"nested": {
"path": "driver.car",
"query": {
"range": {
"driver.car.color": {
"gt": "green"
}
}
}
}
}
]
}
}
}
BTW you don't need the double nesting -- drive.car will work exactly the same as driver -> driver.car.
