• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky ((nang ma) OR (tang ma)) hoi. lieu va cam luc ((va nang) OR (cam nang)) doi cu tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((nang ma) or (tang ma)) hoi. lieu va cam luc ((va nang) OR (cam nang)) doi cu tren".
• Adding a wildcard symbol may retrieve word variants: tu sac ky ((nang ma) or (tang ma)) hoi. lieu va cam luc ((va nang) OR (cam nang)) doi cu tren*.
