• If you are trying to use Boolean operators, they must be ALL CAPS: hoa lang ky ((nang xa) OR (nang ma)) hoi. hieu ve cao ((duc ban) OR (dua ban)) hanh vai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoa lang ky ((nang xa) or (nang ma)) hoi. hieu ve cao ((duc ban) OR (dua ban)) hanh vai cua triet".
