Address locators using the Single House Subaddress style do not provide a 100 match score when searching for addresses with a forward slash in the SubAddr Unit or the Building Unit field.
1. Create a new field in the attribute table.
2. Use the Field Calculator to concatenate the Sub_address_type and Sub_address_unit information together.
3. Assign this field as the SubAddr Type while creating the locator, and do not provide a SubAddr Unit.
