NewDoubleRange(String, Int32, Nullable<Double>, Nullable<Double>, Boolean, Boolean)

Factory that creates a NumericRangeFilter, that filters a System.Double range using the given PrecisionStep. You can have half-open ranges (which are in fact </<= or >/>= queries) by setting the min or max value to null. System.Double.NaN will never match a half-open range, to hit NaN use a query with min == max == System.Double.NaN. By setting inclusive to false, it will match all documents excluding the bounds, with inclusive on, the boundaries are hits, too.

Declaration

public static NumericRangeFilter<double> NewDoubleRange(string field, int precisionStep, double? min, double? max, bool minInclusive, bool maxInclusive)

Parameters

Type	Name	Description
System.String	field
System.Int32	precisionStep
System.Nullable<System.Double>	min
System.Nullable<System.Double>	max
System.Boolean	minInclusive
System.Boolean	maxInclusive

Returns

Type	Description
NumericRangeFilter<System.Double>

NewDoubleRange(String, Nullable<Double>, Nullable<Double>, Boolean, Boolean)

Factory that creates a NumericRangeFilter, that queries a System.Double range using the default PrecisionStep PRECISION_STEP_DEFAULT (4). You can have half-open ranges (which are in fact </<= or >/>= queries) by setting the min or max value to null. System.Double.NaN will never match a half-open range, to hit NaN use a query with min == max == System.Double.NaN. By setting inclusive to false, it will match all documents excluding the bounds, with inclusive on, the boundaries are hits, too.

Declaration

public static NumericRangeFilter<double> NewDoubleRange(string field, double? min, double? max, bool minInclusive, bool maxInclusive)

Parameters

Type	Name	Description
System.String	field
System.Nullable<System.Double>	min
System.Nullable<System.Double>	max
System.Boolean	minInclusive
System.Boolean	maxInclusive

Returns

Type	Description
NumericRangeFilter<System.Double>
