Flexible Range Expansion

Imposes a practical limit on the number of addresses that the Address Validator transformation returns when you set the Ranges to Expand property. You can set the Ranges to Expand property and the Flexible Range Expansion property when you configure the transformation to run in suggestion list mode.

The Ranges to Expand property determines how the transformation returns address suggestions when an input address does not contain house number data. If the input address does not include contextual data, such as a full post code, the Ranges to Expand property can generate a large number of very similar addresses. The Flexible Range Expansion property restricts the number of addresses that the Ranges to Expand property generates for a single address. Set the Flexible Range Expansion property to On when you set the Ranges to Expand property to All.

The following table describes the options on the Flexible Range Expansion property:

Option	Description
On	Address validation limits the number of addresses that the Ranges to Expand property adds to the suggestion list. Default option.
Off	Address validation does not limit the number of addresses that the Ranges to Expand property adds to the suggestion list.

The Address Validator transformation applies the Flexible Range Expansion property in a different way to every address that it returns to the suggestion list. The transformation does not impose a fixed limit on the number of expanded addresses in the list. The transformation also considers the Max Result Count property setting when it calculates the number of expanded addresses to include in the list.
