 * @E_BOOK_QUERY_EQUALS_PHONE_NUMBER: check if a field matches with a value tested
 * using e_phone_number_compare_strings(), the match must be of strenth %E_PHONE_NUMBER_MATCH_EXACT
 * for this query to return any matches.
 * @E_BOOK_QUERY_EQUALS_NATIONAL_PHONE_NUMBER: check if a field matches with a value tested
 * using e_phone_number_compare_strings(), the match must be at least of strength %E_PHONE_NUMBER_MATCH_NATIONAL
 * for this query to return any matches.
 * @E_BOOK_QUERY_EQUALS_SHORT_PHONE_NUMBER: check if a field matches with a value tested
 * using e_phone_number_compare_strings(), the match must be at least of strength %E_PHONE_NUMBER_MATCH_SHORT
 * for this query to return any matches.
 * @E_BOOK_QUERY_REGEX_NORMAL: A regular expression query against contact data normalized with e_util_utf8_normalize(),
 * the normalized data is lower case with any accents removed.
 * @E_BOOK_QUERY_REGEX_RAW: A regular expression query against raw contact data, this is usually slower than
 * a %E_BOOK_QUERY_REGEX_NORMAL as it implies that #EVCard(s) must be parsed in order to get the raw data
 * for comparison.
 * @E_BOOK_QUERY_LAST: End marker for the #EBookQueryTest enumeration, not a valid query test.
 *
 * The kind of test a query created by e_book_query_field_test() shall perform.
