• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sac ky)) tang van hoi. ((hieu va) OR (lieu va)) tham nuoc gia thanh tri cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) OR (sac ky)) tang van hoi. ((hieu va) or (lieu va)) tham nuoc gia thanh tri cua triet".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) OR (sac ky)) tang van hoi. ((hieu va) or (lieu va)) tham nuoc gia thanh tri cua triet*.
