• If you are trying to use Boolean operators, they must be ALL CAPS: co sach ty tang van hoi. ((hieu van) OR (lieu va)) cam tuc va hanh vi ((cua triet) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "co sach ty tang van hoi. ((hieu van) or (lieu va)) cam tuc va hanh vi ((cua triet) OR (su triet))".
• Adding a wildcard symbol may retrieve word variants: co sach ty tang van hoi. ((hieu van) or (lieu va)) cam tuc va hanh vi ((cua triet) OR (su triet))*.
