Java API for multiple sub-aggregations

Hi,

I am trying to find out the JAVA API that supports nested sub-aggregations in ES. However, the current API's doesn't provide the clear implementation.

Req: property1 , property 2 .... property n

Using TermBuilder, when i tried adding the subAggregation of subAggregation, its getting added into the TermsBuilder as list of sub-aggregrations rather than nested sub-aggregations.

Thanks,
Saravanan.

I'm having the same problem and using sub-aggregation of sub-aggregation
but it's difficult to parse response because will have to use many loop and
I think it's not good way

Hi,

A possible solution is :

TermsBuilder termsBuilder = null;
TermsBuilder root = null;
if (!aggregs.isEmpty()) {
for (Aggreg aggreg : aggregs) {
if (aggreg.aggregOk()) {
if (aggreg.isTerms()) {
if (termsBuilder != null) {
TermsBuilder temp = terms(aggreg.getKey()).field(aggreg.getField()).minDocCount(0).size(0);
termsBuilder = termsBuilder.subAggregation(temp);
termsBuilder = temp;
} else {
termsBuilder = terms(aggreg.getKey()).field(aggreg.getField()).minDocCount(0).size(0);
root = termsBuilder;
}
}
}
}
}
termsBuilder = root;
