/**
 * A set of values to handle specific positions for list of names.
 *
 * As for list of names, this helps to follow a specific order based on the
 * count of elements. It is expected that the list has to be between two and
 * five elements. Also, the order of appearance set in the configuration
 * influences how the parsing is carried out.
 *
 * Ordered by first name, the parser works as follows:
 * - 2 elements: firstName lastName
 * - 3 elements: firstName middleName lastName
 * - 4 elements: prefix firstName middleName lastName
 * - 5 elements: prefix firstName middleName lastName suffix
 *
 * Ordered by last name, the parser works as follows:
 * - 2 elements: lastName firstName
 * - 3 elements: lastName firstName middleName
 * - 4 elements: prefix lastName firstName middleName
 * - 5 elements: prefix lastName firstName middleName suffix
 *
 * For example, `Jane Smith` (ordered by first name) is expected to be indexed:
 * `['Jane', 'Smith']`.
