• If you are trying to use Boolean operators, they must be ALL CAPS: vu ban ky tang ((ma hoi) OR (ma hoa)). hieu ((ve cham) OR (va cham)) luc va xanh tri cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ban ky tang ((ma hoi) or (ma hoa)). hieu ((ve cham) OR (va cham)) luc va xanh tri cuu tre*".
