The NumericRangeExpansion element specifies how Informatica Address Verification returns address suggestions when the input address data matches a range of addresses in the same building or street. For example, Address Verification might determine that an input address matches a range of house numbers on a given street. In such a case, Address Verification can return the upper and lower numbers in the available range in a single suggestion.
Address Verification can apply numeric range expansion to house number data, building data, and sub-building data. Address Verification can perform range expansion in QuickCapture mode and Interactive mode.
NumericRangeExpansion Properties
To define how Address Verification handles number ranges, configure the following properties on the NumericRangeExpansion element:
RangesToExpand
Specifies whether to expand number ranges in address suggestions from countries for which individual house number, building, or sub-building values are available in the reference data.
RangeExpansionType
Specifies the scope of range expansion in suggestion lists.
RangesToExpand
The RangesToExpand property has the following options:
All
Expands the house number, building, or sub-building values to match the individual house numbers available in the reference data.
OnlyValid
Expands the ranges only when the reference data contains the complete list of valid numbers in a range.
None
Does not expand any range. The default value is None.
When the complete list of house numbers is not available in the reference address database, OnlyValid works the same way as None.
RangeExpansionType
The RangeExpansionType property has the following options:
Full
Expands all the items in the suggestion list, depending on the current RangesToExpand options.
Flexible
Expands the initial items in the suggestion list, depending on the current RangesToExpand options.
If you set the RangeExpansionType property to Flexible, the internal engine logic decides on the number of results to expand and how many to keep as ranges without exceeding the maximum result count value. Therefore, the suggestion list might contain both expanded and unexpanded ranges if you set the RangeExpansionType property to Flexible.
