How do I write correct query in nested document? - elasticsearch

Question

I have two indices: country and person
PUT person
{
"mappings": {
"properties": {
"info": {
"type": "nested",
"properties": {
"int_val": {"type": "integer"},
"str_val": {"type": "text"},
"field_id": {"type": "keyword"},
"country_id": {"type": "keyword"}
}
}
}
}
}
PUT country
{
"mappings": {
"properties": {
"country_ids": {"type": "keyword"}
}
}
}
PUT country/_doc/user1
{
"country_ids": ["111", "222", "333"]
}
PUT person/_doc/1
{
"info": [
{
"field_id": "1000",
"str_val": "Jack Kotlin",
"country_id": "444"
},
{
"field_id": "1000",
"str_val": "Jack Martin",
"country_id": "333"
},
{
"field_id": "1001",
"str_val": "Jack",
"country_id": "111"
},
{
"field_id": "2000",
"int_val": 30,
"country_id": "444"
},
{
"field_id": "2000",
"int_val": 30,
"country_id": "333"
},
{
"field_id": "2001",
"int_val": 30,
"country_id": "111"
}
]
}
If user1 queries '(field_id=1000 with str_val="Jack") & (field_id=2000 with int_val="Jack")' following result must be return:
{
"info": [
{
"field_id": "1000",
"str_val": "Jack Martin",
"country_id": "333"
},
{
"field_id": "2000",
"int_val": 30,
"country_id": "333"
}
]
}
Help me please!
I wrote a query for single part: (field_id=1000 with str_val="Jack")
GET person/_search
{
"query": {
"nested": {
"path": "info",
"query": {
"bool": {
"filter": [
{
"terms": {
"info.country_id": {
"index": "country",
"id": "user1",
"path": "country_ids"
}
}
}
],
"must": [
{"match": {"info.field_id": "1000"}},
{"match": {"info.str_val": "Jack"}}
]
}
},
"inner_hits": {}
}
},
"_source": false
}
and got a correct result:
{
"took" : 5,
"timed_out" : false,
"_shards" : {
"total" : 1,
"successful" : 1,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : {
"value" : 1,
"relation" : "eq"
},
"max_score" : 1.1530519,
"hits" : [
{
"_index" : "person",
"_id" : "1",
"_score" : 1.1530519,
"inner_hits" : {
"info" : {
"hits" : {
"total" : {
"value" : 1,
"relation" : "eq"
},
"max_score" : 1.1530519,
"hits" : [
{
"_index" : "person",
"_id" : "1",
"_nested" : {
"field" : "info",
"offset" : 1
},
"_score" : 1.1530519,
"_source" : {
"field_id" : "1000",
"str_val" : "Jack Martin",
"country_id" : "333"
}
}
]
}
}
}
}
]
}
}
but I don't know how to write a query for multi part!

The following query will show:
Documents with (id=1000 AND str_field=Jack) AND (id=2000 AND int_field=30)
GET person/_search
{
"query": {
"nested": {
"path": "info",
"query": {
"bool": {
"filter": [
{
"terms": {
"info.country_id": {
"index": "country",
"id": "user1",
"path": "country_ids"
}
}
},
{
"bool": {
"must": [
{
"bool": {
"must": [
{
"term": {
"info.field_id": "2000"
}
},
{
"match": {
"info.int_val": 30
}
}
]
}
},
{
"bool": {
"must": [
{
"term": {
"info.field_id": "1000"
}
},
{
"match": {
"info.str_val": "Jack"
}
}
]
}
}
]
}
}
]
}
},
"inner_hits": {}
}
},
"_source": false
}
