One way that you can boost matching performance is by excluding records from matching operations. When the total number of records the add-on must process is reduced, it can cut down on the total processing time and help improve the overall quality of results by preventing false positive matches. When you configure options to exclude records:
You tell the add-on to look at the values in a specific field.
You specify criterion that determines whether (based on the field value) a record is excluded. For example, you could specify that null values in an Expiration Date field exclude records from matching. The reason being, only products that still have an expiration date are not yet expired and should be matched.
The configuration applies to all available types of matching.
Any record that is excluded from matching is set to <Unset>.
To exclude records from matching:
Navigate to Administration > TIBCO EBX® Match and Merge Add-on > Table activation and settings and open the configuration where you want to exclude records.
Select the Matching policies tab and open the desired matching policy.
Select the Matching fields tab and create a new, or open an existing field.
Use the Exclude records where property to add at least one criteria used to exclude records.
You can select:
equals and is different to enter a specific value that must be the same or different to exclude a record, respectively.
is null or is not null to specify that if the field is missing a value or has a value the record will be excluded, respectively.
Save your changes before exiting.
