• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc sach) OR (dac sac)) ky ((nang xa) OR (nang ma)) hoi. hieu ha nam tuc va thanh tai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc sach) or (dac sac)) ky ((nang xa) OR (nang ma)) hoi. hieu ha nam tuc va thanh tai cua te*".
