        examples:
          terms:
            summary: Terms
            value: terms(fields=(access,tags,source))
            description: An aggregation that analyzes matching items by the unique values of the specified fields. Returns buckets by field and unique value. The mandatory "fields" parameter is a comma-separated list of field names to aggregate on.
          max:
            summary: Max
            value: max(fields=(totalReplies, totalReactions))
            description: An aggregation that calculates the maximum value of one or more fields across all matching items. The mandatory "fields" parameter is a comma-separated list of field names to aggregate on.
          min:
            summary: Min
            value: min(fields=(totalReplies, totalReactions))
            description: An aggregation that calculates the minimum value of one or more fields across all matching items. The mandatory "fields" parameter is a comma-separated list of field names to aggregate on.
          avg:
            summary: Avg
            value: avg(fields=(totalReactions, totalReplies))
            description: An aggregation that calculates the averages value of one or more fields across all matching items. The mandatory "fields" parameter is a comma-separated list of field names to aggregate on.
          histogram:
            summary: Histogram
            value: histogram(fields=(totalReplies,totalReactions), interval=5)
            description: An aggregation that groups items into buckets based on a numeric field. The mandatory "fields" parameter are the numeric fields to aggregate on. The mandatory "interval" parameter is the interval to use for bucketing, and has a minimum value of 0.1.
          date_histogram:
            summary: Date Histogram
            value: date_histogram(fields=(createdAt, updatedAt),interval=month,bycreator=terms(fields=(creator,editor)))
            description: 'An aggregation that groups items into buckets based on a date field. The mandatory "fields" parameter are the date fields to aggregate on. The mandatory "interval" parameter is the time interval to use for bucketing. Valid intervals are: "year", "month", "week", and "day". You can also specify a number of days from 1-99 inclusive, e.g. "14d" for fourteen days. Finally, sub-aggregations can provided that summate discussion post data on a per-bucket basis. This example aggregates posts based on the createdAt and updatedAt fields and, for each, further sub-aggregating by creator, and editor.'
          geohash:
            summary: Geohash
            value: geohash(fields=(geometry), precision=6, byCreator=terms(fields=(creator)), byCreatedDate=date_histogram(fields=(createdAt), interval=month), avgSentiment=avg(fields=(sentiment)))
            description: An aggregation that groups items into buckets based on a geohash on a geospatial field. The mandatory "fields" parameter are the geospatial fields for which to aggregate on. "Precision" can be optionally provided (defaults to 5) to allow for hashing with various geospatial precisions (https://en.wikipedia.org/wiki/Geohash#Digits_and_precision_in_km). Finally, sub-aggregations can provided that summate discussion post data on a per-geohash basis. This example geohashes posts based on the geometry field, further sub-aggregating by creator, post creation date, and average sentiment.
