CalendarInterval

Declaration
public Union<DateInterval?, DateMathTime> CalendarInterval { get; set; }
Property Value
Type Description
Union<DateInterval?, DateMathTime>

ExtendedBounds

Extend the bounds of the date histogram beyond the data itself, forcing the aggregation to start building buckets on a specific min and/or max value. Using extended bounds only makes sense when MinimumDocumentCount is 0 as empty buckets will never be returned if it is greater than 0.

Declaration
public ExtendedBounds<DateMath> ExtendedBounds { get; set; }
Property Value
Type Description
ExtendedBounds<DateMath>

Field

The field to target

Declaration
public Field Field { get; set; }
Property Value

FixedInterval

The fixed interval to use when bucketing documents

Declaration
public Time FixedInterval { get; set; }
Property Value
Type Description
Time

Format

Return a formatted date string as the key instead an epoch long

Declaration
public string Format { get; set; }
Property Value
Type Description
string

HardBounds

The hard_bounds is a counterpart of extended_bounds and can limit the range of buckets in the histogram. It is particularly useful in the case of open data ranges that can result in a very large number of buckets.

Declaration
public HardBounds<DateMath> HardBounds { get; set; }
Property Value
Type Description
HardBounds<DateMath>

MinimumDocumentCount

The minimum number of documents that a bucket must contain to be returned in the response. The default is 0 meaning that buckets with no documents will be returned.

Declaration
public int? MinimumDocumentCount { get; set; }
Property Value
Type Description
int?

Missing

Defines how to treat documents that are missing a value. By default, they are ignored, but it is also possible to treat them as if they have a value.

Declaration
public DateTime? Missing { get; set; }
Property Value
Type Description
DateTime?

Offset

Change the start value of each bucket by the specified positive (+) or negative offset (-) duration, such as 1h for an hour, or 1d for a day.

Declaration
public string Offset { get; set; }
Property Value
Type Description
string

Order

Defines an order in which returned buckets are sorted. By default the returned buckets are sorted by their key ascending.

Declaration
public HistogramOrder Order { get; set; }
Property Value
Type Description

Script

A script to execute to provide custom computation

Declaration
public IScript Script { get; set; }
Property Value
Type Description

TimeZone

Used to indicate that bucketing should use a different time zone. Time zones may either be specified as an ISO 8601 UTC offset (e.g. +01:00 or -08:00) or as a timezone id, an identifier used in the TZ database like America/Los_Angeles.

Declaration
public string TimeZone { get; set; }
Property Value
Type Description
