• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky ((tang ma) OR (tang van)) hoa. ((hieu va) OR (lieu va)) da duoc ma tinh viec cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((tang ma) OR (tang van)) hoa. ((hieu va) or (lieu va)) da duoc ma tinh viec cua triet".
• Adding a wildcard symbol may retrieve word variants: tu sac ky ((tang ma) OR (tang van)) hoa. ((hieu va) or (lieu va)) da duoc ma tinh viec cua triet*.
