MATCH_OPTIONS Control

MATCH_OPTIONS Control

Use the MATCH_OPTIONS control to define the options for a specific field.
The
MATCH_OPTIONS
control uses the following syntax:
MATCH_OPTIONS=(fieldname:option,...)
You can use the following options for the fields:
Above
Use the
above
option to set the match score to 100 when the match score exceeds the specified threshold value.
The
MATCH_OPTIONS
control uses the following format for the
above
option:
MATCH_OPTIONS=(fieldname:above=<value>)
In the following example, the
above
option changes the match score that is above 70 to 100.
MATCH_OPTIONS=(Person_name:above=70)
You can't use the
above
and
below
options simultaneously in the
MATCH_OPTIONS
control.
Below
Use the
below
option to set the match score to 0 when the match score is below the specified threshold value.
The
MATCH_OPTIONS
control uses the following format for the
below
option:
MATCH_OPTIONS=(fieldname:below=<value>)
In the following example, the
below
option changes the match score that is below 60 to 0.
MATCH_OPTIONS=(Person_name:below=60)
You can't use the
above
and
below
options simultaneously in the
MATCH_OPTIONS
control.
Date
The
Date
field accepts the
Date_Format
,
rangeopt
, and
rangesel
options.
The
MATCH_OPTIONS
control uses the following format for the
Date_Format
option:
MATCH_OPTIONS=(DATE:Date_Format=<DDMMYY>|<MMDDYY>|<YYMMDD>)
The
MATCH_OPTIONS
control uses the following format for the
rangeopt
, and
rangesel
options:
MATCH_OPTIONS=(DATE:rangeopt=1,rangesel=1)
Configure the
MATCH_OPTIONS=(Date:rangeopt=1,rangesel=1)
control to set the
RANGEOPT
and
RANGESEL
options for testing and runtime tuning.
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.
