• If you are trying to use Boolean operators, they must be ALL CAPS: gioi hoa binh - ((hanh hang) OR (thanh hang)) cua han thong dan ((toan cau) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "gioi hoa binh - ((hanh hang) OR (thanh hang)) cua han thong dan ((toan cau) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: gioi hoa binh - ((hanh hang) OR (thanh hang)) cua han thong dan ((toan cau) or (toan cao))*.
