• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu cach) OR (thu canh)) tu sang ma hoi. hieu ve ((cam luc) OR (cau luc)) va hanh via cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu cach) or (thu canh)) tu sang ma hoi. hieu ve ((cam luc) OR (cau luc)) va hanh via cua triet*".
