  • Patent number: 9336283
    Abstract: A method for data sensitive filtering in a patient database searches includes providing a search criteria comprising one or more search locator fields, determining a retrieval formula from the search criteria that maximizes error tolerance in the search criteria while satisfying a predefined response time requirement, and retrieving candidate records from the database. If no retrieval formula can be found that satisfies the response time requirements, the method includes requesting additional search criteria, scoring each candidate record by comparing a search criteria locator field with a corresponding retrieved record field, and determining whether the score of the candidate record exceeds a predefined threshold. If the candidate score does exceed the threshold, the candidate record is added to a list of records to be returned in response to the search criteria.
