• If you are trying to use Boolean operators, they must be ALL CAPS: bo sach lo lang xa hoi. thi van ha ((tuc va) OR (truc va)) thanh vi ((cua triet) OR (ca tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "bo sach lo lang xa hoi. thi van ha ((tuc va) OR (truc va)) thanh vi ((cua triet) or (ca tren))".
• Adding a wildcard symbol may retrieve word variants: bo sach lo lang xa hoi. thi van ha ((tuc va) OR (truc va)) thanh vi ((cua triet) or (ca tren))*.
