bucketOrd
- The ordinal of the bucket this aggregator belongs to, assuming this aggregator is not a top level aggregator.
Typically, aggregators with #bucketAggregationMode
set to Aggregator.BucketAggregationMode.MULTI_BUCKETS
will heavily depend on this ordinal. Other aggregators may or may not use it and can see this ordinal as just
an extra information for the aggregation context. For top level aggregators, the ordinal will always be
equal to 0.IOException
