• If you are trying to use Boolean operators, they must be ALL CAPS: te sach thu ((bang xa) OR (mang xa)) hoi. hieu ve cac xuc van hanh ((de cua) OR (te cua)) cu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach thu ((bang xa) or (mang xa)) hoi. hieu ve cac xuc van hanh ((de cua) OR (te cua)) cu".
