public void writeTo(StreamOutput out)
             throws IOException

Description copied from interface: Writeable

Write this into the StreamOutput.

Throws:

IOException

fieldName

public String fieldName()

Returns the geo point like field the distance based sort operates on.

 double lon)

The point to create the range distance facets from.

Parameters:

lat - latitude.

lon - longitude.

The point to create the range distance facets from.

Parameters:

points - reference points.

points

public GeoPoint[] points()

Returns the points to create the range distance facets from.

geoDistance

public GeoDistanceSortBuilder geoDistance(GeoDistance geoDistance)

The geo distance type used to compute the distance.

geoDistance

public GeoDistance geoDistance()

Returns the geo distance type used to compute the distance.

unit

public GeoDistanceSortBuilder unit(DistanceUnit unit)

The distance unit to use. Defaults to DistanceUnit.METERS

unit

public DistanceUnit unit()

Returns the distance unit to use. Defaults to DistanceUnit.METERS

validation

public GeoDistanceSortBuilder validation(GeoValidationMethod method)

Sets validation method for this sort builder.

validation

public GeoValidationMethod validation()

Returns the validation method to use for this sort builder.

sortMode

public GeoDistanceSortBuilder sortMode(SortMode sortMode)

Defines which distance to use for sorting in the case a document contains multiple geo points. Possible values: min and max

sortMode

public SortMode sortMode()

Returns which distance to use for sorting in the case a document contains multiple geo points.

setNestedFilter

@Deprecated
public GeoDistanceSortBuilder setNestedFilter(QueryBuilder nestedFilter)

Deprecated.

set nested sort with setNestedSort(NestedSortBuilder) and retrieve with getNestedSort()

Sets the nested filter that the nested objects should match with in order to be taken into account for sorting.

getNestedFilter

@Deprecated
public QueryBuilder getNestedFilter()

Deprecated.

set nested sort with setNestedSort(NestedSortBuilder) and retrieve with getNestedSort()

Returns the nested filter that the nested objects should match with in order to be taken into account for sorting.

setNestedPath

@Deprecated
public GeoDistanceSortBuilder setNestedPath(String nestedPath)

Deprecated.

set nested sort with setNestedSort(NestedSortBuilder) and retrieve with getNestedSort()

Sets the nested path if sorting occurs on a field that is inside a nested object. By default when sorting on a field inside a nested object, the nearest upper nested object is selected as nested path.

getNestedPath

@Deprecated
public String getNestedPath()

Deprecated.

set nested sort with setNestedSort(NestedSortBuilder) and retrieve with getNestedSort()

Returns the nested path if sorting occurs on a field that is inside a nested object. By default when sorting on a field inside a nested object, the nearest upper nested object is selected as nested path.

Returns the NestedSortBuilder

setNestedSort

public GeoDistanceSortBuilder setNestedSort(NestedSortBuilder nestedSort)

Sets the NestedSortBuilder to be used for fields that are inside a nested object. The NestedSortBuilder takes a `path` argument and an optional nested filter that the nested objects should match with in order to be taken into account for sorting.
