When using a complete date of birth in a query, by how many years may the search adjust the records?

When a complete date of birth is utilized in a query, the search adjusts the records by three years. This adjustment accounts for potential inaccuracies or variations in the recorded birth date while still ensuring that relevant records are retrieved. Using a three-year margin allows the query to effectively broaden its scope, capturing records that may have slight discrepancies in birth dates due to data entry errors or differences in reporting. This approach helps ensure that individuals who might be listed in the system with a birth date that is one or two years earlier or later than the exact date entered are still included in the search results, enhancing the accuracy and comprehensiveness of the information retrieved.
