• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu cach) OR (thu canh)) tu san ma hoi. ((hieu ve) OR (hieu va)) cam vuc ban hanh vi hoa viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu cach) OR (thu canh)) tu san ma hoi. ((hieu ve) or (hieu va)) cam vuc ban hanh vi hoa viet*".
