• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) ((ky lang) OR (ky tang)) xa hoi. hieu vien cap nuoc va nhanh tai cuc tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (thu sach)) ((ky lang) OR (ky tang)) xa hoi. hieu vien cap nuoc va nhanh tai cuc tre~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (thu sach)) ((ky lang) OR (ky tang)) xa hoi. hieu vien cap nuoc va nhanh tai cuc tre*.
