SEARCH and FILE Controls

Use the SEARCH and FILE controls to specify the field names and their offset and length pairs in the scatter or gather format for the data in the

Search Data

and

File Data

fields. If you do not specify the offset and length pairs for the field names, SSA-NAME3 considers the data in the tagged data format.

You can extend any of the key fields and set the weight for the extended fields. The extended fields use the algorithm of the key fields. Use the extended fields to override the weight of the key fields in the run time. You can also specify the type of matching to perform between the data in the

Search Data

and

File Data

fields.

Additionally, you can use the

above

below

options for the extended fields to set their match score to 100 or 0.

Above: Use the
above
option to set the match score to 100 when the match score exceeds the specified threshold value.
The SEARCH and FILE controls use the following format for the
above
option:
SEARCH=<Field Name>(<Field ID>;above:<value>),<offset>,<length> FILE=<Field Name>,<offset>,<length>

In the following example, the
above
option changes the match score that is above 70 to 100.
SEARCH=Person_name(0;above:70),0,4 FILE=Person_name,0,4

You can't use the
above
and
below
options simultaneously in the SEARCH and FILE controls.

Below: Use the
below
option to set the match score to 0 when the match score is below the specified threshold value.
The SEARCH and FILE controls use the following format for the
below
option:
SEARCH=<Field Name>(<Field ID>;below:<value>),<offset>,<length> FILE=<Field Name>,<offset>,<length>

In the following example, the
below
option changes the match score that is below 60 to 0.
SEARCH=Person_name(0;below=60),0,4 FILE=Person_name,0,4

You can't use the
above
and
below
options simultaneously in the SEARCH and FILE controls.

You can use the following matching types:

Exact matching. Returns 100% score only if the search data values match with the file data values.

Fuzzy matching. Returns 0 to 100% score based on how close the search data and file data values match.

Inexact matching. Returns 100% score if the search data values do not match with the file data values.

Range matching. Returns 100% score if the search data and file data values are within the specified range.

If you specify different matching types in the SEARCH and FILE parameters, the matching type that you specify in the SEARCH parameter takes precedence.
