Elastic Search : Restricting the search result in array - elasticsearch

Question

My index metadata :
{
"never": {
"aliases": {},
"mappings": {
"userDetails": {
"properties": {
"Residence_address": {
"type": "nested",
"include_in_parent": true,
"properties": {
"Address_type": {
"type": "string",
"analyzer": "standard"
},
"Pincode": {
"type": "string",
"analyzer": "standard"
},
"address": {
"type": "string",
"analyzer": "standard"
}
}
}
}
}
},
"settings": {
"index": {
"creation_date": "1468850158519",
"number_of_shards": "5",
"number_of_replicas": "1",
"version": {
"created": "1060099"
},
"uuid": "v2njuC2-QwSau4DiwzfQ-g"
}
},
"warmers": {}
}
}
My setting :
POST never
{
"settings": {
"number_of_shards" : 5,
"analysis": {
"analyzer": {
"standard": {
"tokenizer": "keyword",
"filter" : ["lowercase","reverse"]
}
}
}
}
}
My data :
{
"took": 1,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
},
"hits": {
"total": 1,
"max_score": 0.375,
"hits": [
{
"_index": "never",
"_type": "userDetails",
"_id": "1",
"_score": 0.375,
"_source": {
"Residence_address": [
{
"address": "Omega Residency",
"Address_type": "Owned",
"Pincode": "500004"
},
{
"address": "Collage of Engineering",
"Address_type": "Rented",
"Pincode": "411005"
}
]
}
}
]
}
}
My query :
POST /never/_search?pretty
{
"query": {
"match": {
"Residence_address.address": "Omega"
}
}
}
My Result :
{
"took": 1,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
},
"hits": {
"total": 1,
"max_score": 0.375,
"hits": [
{
"_index": "never",
"_type": "userDetails",
"_id": "1",
"_score": 0.375,
"_source": {
"Residence_address": [
{
"address": "Omega Residency",
"Address_type": "Owned",
"Pincode": "500004"
},
{
"address": "Collage of Engineering",
"Address_type": "Rented",
"Pincode": "411005"
}
]
}
}
]
}
}
Is there any way to restrict my result to only object containing address = Omega Residency and NOT the other object having address = Collage of Engineering?

Answer 1

You can only do it with nested query and inner_hits. I see that you have include_in_parent: true and not using nested queries though. If you only want to get the matched nested objects you'd need to use inner_hits from nested queries:
GET /never/_search?pretty
{
"_source": false,
"query": {
"nested": {
"path": "Residence_address",
"query": {
"match": {
"Residence_address.address": "Omega Residency"
}
},
"inner_hits" : {}
}
}
}
