• If you are trying to use Boolean operators, they must be ALL CAPS: su sach thu tang van hoi. hieu ve chat ((xuc va) OR (tuc va)) dinh vi ((cua triet) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach thu tang van hoi. hieu ve chat ((xuc va) OR (tuc va)) dinh vi ((cua triet) or (su triet))".
