java.lang.Object

org.apache.lucene.queryparser.xml.builders.NumericRangeFilterBuilder

All Implemented Interfaces:

FilterBuilder

public class NumericRangeFilterBuilder
extends java.lang.Object
implements FilterBuilder

Creates a NumericRangeFilter. The table below specifies the required attributes and the defaults if optional attributes are omitted. For more detail on what each of the attributes actually do, consult the documentation for NumericRangeFilter:

Attribute name	Values	Required	Default
fieldName	String	Yes	N/A
lowerTerm	Specified by type	Yes	N/A
upperTerm	Specified by type	Yes	N/A
type	int, long, float, double	No	int
includeLower	true, false	No	true
includeUpper	true, false	No	true
precisionStep	Integer	No	4

If an error occurs parsing the supplied lowerTerm or upperTerm into the numeric type specified by type, then the error will be silently ignored and the resulting filter will not match any documents.
