Elasticsearch connect range and term to same array item - elasticsearch

Question

I have a user document with a field called experiences which is an array of objects, like:
{
"experiences": [
{
"end_date": "2017-03-02",
"is_valid": false
},
{
"end_date": "2015-03-02",
"is_valid": true
}
]
}
With this document I have to search users where end date is in last year and is_valid is true.
At this time I have a query -> bool and I add two must there, one range for the end_date and one term for the is_valid.
{
"query": {
"bool": {
"must": {
"term": {
"experiences.is_valid": true
},
"range": {
"experiences.end_date": {
"gte": "now-1y",
"lte": "now"
}
},
}
}
}
}
The result is that this user is selected because he has an end_date in the last year (the first exp.) and another exp. with is_valid true.
Of course this is not what I need, because I need that end_date and is_valid must be referenced to the same object, but how can we do this on Elasticsearch?
Mapping:
"experiences": {
"properties": {
"comment": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"end_date": {
"type": "date"
},
"id": {
"type": "long"
},
"is_valid": {
"type": "boolean"
},
"start_date": {
"type": "date"
}
}
}

You need to change experiences type to Nested data type.
Then apply nested query :
{
"query": {
"nested": {
"path": "experiences",
"query": {
"bool": {
"must": [
{
"term": {
"experiences.is_valid": true
}
},
{
"range": {
"experiences.end_date": {
"gte": "now-1y",
"lte": "now"
}
}
}
]
}
}
}
}
}
This is due to the way arrays of objects are flattened in Elasticsearch.
