Aggregation problem

Elastic Stack Elasticsearch
1

Hey guys,

I have this mapping:

GET ckdocuments/msv/_mapping

{
"ckdocuments": {
"mappings": {
"msv": {
"properties": {
"MSV": {
"properties": {
"country": {
"type": "string",
"index": "not_analyzed"
},
"date": {
"type": "date",
"format": "YYYY-MM-dd HH:mm:ss"
},
"hits": {
"type": "nested",
"properties": {
"click_type": {
"type": "string",
"index": "not_analyzed"
}
}
}
}
},
"c": {
"type": "string",
"index": "not_analyzed"
},
"doc_creation_time": {
"type": "date",
"format": "YYYY-MM-dd HH:mm:ss"
},
"views": {
"properties": {
"country": {
"type": "string"
},
"date": {
"type": "date",
"format": "YYYY-MM-dd HH:mm:ss"
},
"hits": {
"properties": {
"click_type": {
"type": "string"
}
}
}
}
}
}
}
}
}
}

Wih these three docs:

PUT ckdocuments/msv/1
{
"c":"a",
"MSV" :
[
{
"country" : "US",
"date" : "2013-01-01 00:00:00",
"hits" : [
{
"click_type" : "click"
}
]
}
],
"views":[
{
"country" : "US",
"date" : "2013-01-01 00:00:00",
"hits" : [
{
"click_type" : "click"
}
]
},
{
"country" : "IL",
"date" : "2013-01-01 00:00:00",
"hits" : [
{
"click_type" : "click"
}
]
}
]
}

PUT ckdocuments/msv/2
{
"doc_creation_time" : "2013-01-01 00:00:00",
"MSV" :
[
{
"country" : "IL",
"date" : "2013-01-01 00:00:00",
"hits" : [
{
"click_type" : "pixel"
}
]
},
{
"country" : "US",
"date" : "2013-01-02 00:00:00",
"hits" : [
{
"click_type" : "click"
}
]
}
],
"views":[
{
"country" : "US",
"date" : "2013-01-01 00:00:00",
"hits" : []
},
{
"country" : "US",
"date" : "2013-01-01 00:00:00",
"hits" : [
{
"click_type" : "pixel"
},
{
"click_type" : "pixel"
}
]
},
{
"country" : "US",
"date" : "2013-01-02 00:00:00",
"hits" : [
{
"click_type" : "click"
}
]
}
]
}

PUT ckdocuments/msv/3
{
"MSV" :
[
{
"country" : "IL",
"date" : "2013-01-01 00:00:00",
"hits" : [
{
"click_type" : "click"
}
]
}
],
"views":[
{
"country" : "US",
"date" : "2013-01-01 00:00:00",
"hits" : [
{
"click_type" : "click"
}
]
},
{
"country" : "IL",
"date" : "2013-01-01 00:00:00",
"hits" : [
{
"click_type" : "click"
}
]
}
]
}

When I run:

GET /ckdocuments/msv/_search
{
"aggregations": {
"MSV":{
"aggs":{
"terms":{
"field" : "MSV.country"
}
}
}
},
"size":0
}
}

I get these results:

{
"took": 1,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
},
"hits": {
"total": 3,
"max_score": 0,
"hits": []
}
}

I just can't understand why the aggregation sperate the results to
countries..
Do you have any idea?

Thnx Niv

Hi,

Your request is not valid, it should be

GET /ckdocuments/msv/_search
{
"aggregations": {
"MSV":{
"terms":{
"field" : "MSV.country"
}
}
},
"size":0
}
}

The next release of Elasticsearch will be less resilient to malformed
aggregations, so you will hopefully get an error instead of just getting
empty aggregations.
