The search area options set the search constraints to use when matching, such as to a city,
finance area, or within a specified search radius distance that can be limited to the
input state. The search area options can assist in finding a match when the input
address contains limited or inaccurate city or ZIP Code information.
The following
example illustrates the different match results for an input address that contains
an incorrect ZIP Code when setting the Search Area to City, then to
Finance Area.
| Input Address |
Match with Search Area set to City |
Match with Search Area set to Finance Area |
|---|
100 Main St
East Aurora, NY 14166
Input address has an incorrect ZIP Code.
|
100 MAIN ST
EAST AURORA NY 14052-1633
Match is made to East Aurora 14052 as there is no candidate in the 14166 input ZIP Code.
|
100 MAIN ST
DUNKIRK NY 14048-1844
Same finance area as the input ZIP Code 14166.

Description

Option.FIND_SEARCH_AREA
|
Note: In CASS match mode, only the search area options described
in FIND_SEARCH_AREA_DEFAULT
are available.
- FIND_SEARCH_AREA_DEFAULT
- The impact of the FIND_SEARCH_AREA_DEFAULT
setting depends on the match mode you're using
for matching.
When Option.FIND_SEARCH_AREA_DEFAULT is set
and you're matching using either
CASS or Relaxed
match mode, the search area is determined based on
the Option.CentroidPreference setting: - If Option.CentroidPreference =
AllCentroids, the
FIND_SEARCH_AREA_CITY search
area is used.
- If Option.CentroidPreference is set to
either NoCentroids or
AddressUnavailable, the
FIND_SEARCH_AREA_FINANCE
search area is used.
When
FIND_SEARCH_AREA_DEFAULT is
set and you're matching using any other match mode -
Custom, Exact,
Close or
Interactive - the
FIND_SEARCH_AREA_FINANCE
search area is used.
- FIND_SEARCH_AREA_FINANCE
- Searches the entire Finance Area for possible
streets.
Note: This option has no effect when
performing a ZIP centroid match or a geographic
geocode.
- FIND_SEARCH_AREA_CITY
- Searches the specified city.
- FIND_SEARCH_AREA_EXPANDED
- Enables the setting of the search radius distance to use
when matching. See
Option.FIND_SEARCH_AREA_DISTANCE
below.
- FIND_EXPND_SRCH_LIM_TO_STATE
- Limits the search to the state, within the search radius
distance. The default search radius is 25 miles.
