ElasticSearch 0.90.2 : terms facet & nested type

Damien_Ferey · August 12, 2013, 1:55pm

Hello,

I've a simple object with nested type, and I would like to have a facet
that returns terms from this nested object.

I've posted details here (mapping, data in ElasticSearch, and java code to
build facet request) :

createindex.sh

#!/bin/sh

curl -XDELETE http://localhost:9200/records
curl -XPOST http://localhost:9200/records
curl -XPUT http://localhost:9200/records/record/_mapping -d "`cat mapping.json`"
curl -XPUT http://localhost:9200/records/record/1 -d "`cat record-1.json`"
curl -XPUT http://localhost:9200/records/record/2 -d "`cat record-2.json`"

mapping.json

{
    "record": {
        "properties": {
            "id": {"type" : "long"},
            "reference" : {"type" : "string", "index": "not_analyzed"},    
            
            "situations": {
                "type": "nested",
                "properties": {
                    "beginDate": {"type" : "date"},

record-1.json

{
    "id": 1,
    "reference": "RECORD-1",
    "situations": [
        {
            "beginDate": 1136847600000,
            "endDate": 32472140400000,
            "type": "FOO"
        }
    ],

This file has been truncated. show original

There are more than three files. show original

When I try a matchall with the facet query, Elasticsearch returns me the
following:

{
"facet_situation": {

"entries": [ ],
"name": "facet_situation",
"totalCount": 0,
"otherCount": 0,
"missingCount": 0

}

Do you have an idea ?
