The organization must decide the weight to be assigned to each search criterion defined, i.e., how important the search criterion is in determining a match for a client. For example, if the organization has defined three search criteria, First Name, Last Name and Date of Birth, First Name may be weighted at 20, Last Name may be weighted at 30, and Date of Birth may be weighted at 50. The weights are used to determine a score for a registered person returned by the search. The score determines whether the person is a conclusive match, an inconclusive match, or not a match, based on the thresholds configured in System Administration.
