• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ty) OR (sach thu)) hang x ho. hieu ve cac duc ((va thanh) OR (va tinh)) dan cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ty) OR (sach thu)) hang x ho. hieu ve cac duc ((va thanh) or (va tinh)) dan cua te*".
