Cannot access parent document field in nested document aggration

Elastic Stack Elasticsearch

Maybe someone will find it useful.

Finally I've found solution, -- reverse_nested
http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-aggregations-bucket-reverse-nested-aggregation.html
aggregation (new in 1.2.0) is what I was needed. Here is my example solved.

curl -XPOST "http://localhost:9200/emotions/emotion/_search?pretty=true" -d
'{
"aggregations": {
"emotionAggr": {
"nested": {
"path": "companyEmotions"
},
"aggregations": {
"emotionAggr2": {
"filter": {
"term": {"companyEmotions.company": "foo"}
},
"aggregations": {
"emotionAggr3": {
"terms": {
"field": "companyEmotions.emotion"
},
"aggregations": {
"emotionAggr4": {
"reverse_nested": {
},
"aggregations": {
"emotionAggr5": {
"sum": {"script":
"doc["count"].value + 1"}
}
}
}
}
}
}
}
}
}
}
}'

Thanks, Viacheslav.
