+// ValueCountAggregation is a single-value metrics aggregation that counts
+// the number of values that are extracted from the aggregated documents.
+// These values can be extracted either from specific fields in the documents,
+// or be generated by a provided script. Typically, this aggregator will be
+// used in conjunction with other single-value aggregations.
+// For example, when computing the avg one might be interested in the
+// number of values the average is computed over.
+// See: https://www.elastic.co/guide/en/elasticsearch/reference/6.0/search-aggregations-metrics-valuecount-aggregation.html
