• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sac ky)) dang xa hoi. ((hieu vien) OR (hieu hien)) bac thue va thanh van cho tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) or (sac ky)) dang xa hoi. ((hieu vien) OR (hieu hien)) bac thue va thanh van cho tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) or (sac ky)) dang xa hoi. ((hieu vien) OR (hieu hien)) bac thue va thanh van cho tre*.
