• If you are trying to use Boolean operators, they must be ALL CAPS: ban hang ((khoa lien) OR (khoa tieng)) ket luan trieu thi minh doanh ((hoan hien) OR (hoan thien)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "ban hang ((khoa lien) or (khoa tieng)) ket luan trieu thi minh doanh ((hoan hien) OR (hoan thien))".
• Adding a wildcard symbol may retrieve word variants: ban hang ((khoa lien) or (khoa tieng)) ket luan trieu thi minh doanh ((hoan hien) OR (hoan thien))*.
