I am doing term aggregation based on field [type] like below but elastic is returning only 1 term count instead of 2 it is not doing nested object aggregation i.e under comments.data.comments[is a list] under this i have 2 type.
{
"aggs": {
"genres": {
"terms": {
"field": "comments.data.comments.type"
}
}
}
}
Gotta utilize the nested field type:
PUT events
{
"mappings": {
"properties": {
"events": {
"type": "nested",
"properties": {
"ecommerceData": {
"type": "nested",
"properties": {
"comments": {
"type": "nested",
"properties": {
"recommendationType": {
"type": "keyword"
}
}
}
}
}
}
}
}
}
}
POST events/_doc
{
"events": [
{
"eventId": "1",
"ecommerceData": [
{
"comments": [
{
"rank": 1,
"recommendationType": "abc"
},
{
"rank": 1,
"recommendationType": "abc"
}
]
}
]
}
]
}
GET events/_search
{
"size": 0,
"aggs": {
"genres": {
"nested": {
"path": "events.ecommerceData.comments"
},
"aggs": {
"nested_comments_recomms": {
"terms": {
"field": "events.ecommerceData.comments.recommendationType"
}
}
}
}
}
}
ecommerceData to recommendationData so make sure you change it in the mapping too.curl -XDELETE ...
