Number of Real-Time Possible Duplicates

This setting controls the maximum number of possible duplicates that can be presented through a real-time interface, such as the Possible Duplicated popup window in Customer Center or the response to the REST findDuplicates API. The underlying profile option is ORA_ZCQ_MAX_CANDIDATES.

Before changing the Number of Real-Time Possible Duplicates setting, you must consider these points:

• The default value of 20 candidates is usually an optimal balance of performance, completeness, and usability.
• Increasing the number of returned candidates above the default value may affect the performance of real-time interfaces.
• Possible Duplicates are returned in descending order of their match score, thus the highest quality match candidates are presented first.
• Keep in mind how many possible duplicates your users are likely to review.
