MATCH_OPTIONS Control

Use the MATCH_OPTOINS control to define the options for a specific field.

The

MATCH_OPTIONS

control uses the following syntax:

MATCH_OPTIONS=(fieldname:option,...)

Use the

MATCH_OPTIONS

control for the following fields:

Date: The
Date
field accepts the
Date_Format
option. The
MATCH_OPTIONS
control uses the following format for the
Date_Format
option:

MATCH_OPTIONS=DATE:Date_Format=<DDMMYY>|<MMDDYY>|<YYMMDD>

The values are not case sensitive.
Geocode: The
Geocode
field accepts the
FORMAT
and
RADIUS
options. The
MATCH_OPTIONS
control uses the following format for the
FORMAT
and
RADIUS
options:
MATCH_OPTIONS=GEOCODE:FORMAT=1,GEOCODE:RADIUS=10000

The
FORMAT
option indicates the order of the latitude and longitude coordinates that you specify.

If
GEOCODE:FORMAT=1
, SSA-NAME3 considers the geographic coordinates in the following order:

*Geocode*<Longitude> <Latitude>***

If
GEOCODE:FORMAT=0
, SSA-NAME3 considers the geographic coordinates in the following order:

*Geocode*<Latitude> <Longitude>***

The default value is 0.

The
RADIUS
option indicates the search radius to generate keys according to the latitude and longitude coordinates that you specify. The default value is 1000 m, and the default unit is meter.

Use the following guidelines when you specify the geocode radius:
SSA-NAME3 considers the radius to be in meters even if you specify any other unit.
SSA-NAME3 ignores the decimal values and uses the whole number as the radius. For example, if you specify the radius as 850.8, SSA-NAME3 considers the radius as 850.; SSA-NAME3 ignores any incorrect or unrecognised options in the
MATCH_OPTIONS
control and proceeds with matching, which might result in unexpected scores.
