• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc ((sach ky) OR (sac ky)) nang xa hoi. ((hieu va) OR (hieu qua)) chat tuc va hanh dai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc ((sach ky) OR (sac ky)) nang xa hoi. ((hieu va) or (hieu qua)) chat tuc va hanh dai cua te*".
