  • inputting a search string, comprising at least one search term, to a user interface;

    testing the search string against the data records using an ordered sequence of search algorithms, the search algorithms being used sequentially and in order, wherein each search algorithm compares the search string against the data records to identify matching data records;

    after application of each search algorithm, terminating the test if at least one matching data record is identified by using the respective search algorithm;

    upon terminating the test, compiling a list of identified data records; and
