• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((ty sang) OR (duy sang)) lap hai. ((hieu ve) OR (lieu va)) cam tuc va danh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((ty sang) OR (duy sang)) lap hai. ((hieu ve) or (lieu va)) cam tuc va danh vi cua te".
