• If you are trying to use Boolean operators, they must be ALL CAPS: tu bai ke mang lai hoi. hieu sau chat luc va hanh vi ((cua te) OR (((cua tu) OR (cua tuc)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu bai ke mang lai hoi. hieu sau chat luc va hanh vi ((cua te) or (((cua tu) OR (cua tuc))))".
