• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thu ((hang ma) OR (hang va)) hoi. hieu qua ca su va thanh ((lap cua) OR (lam cua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thu ((hang ma) OR (hang va)) hoi. hieu qua ca su va thanh ((lap cua) or (lam cua)) te*".
