• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sac ky)) mang may hoi. hieu ve cham ((luc va) OR (tuc va)) phan lap cua tuc*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sac ky)) mang may hoi. hieu ve cham ((luc va) or (tuc va)) phan lap cua tuc*".
