• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sang - ((thanh truong) OR (thanh phuong)) va nang cong ((manh toan) OR (van toan)) cao~.
• Adding a wildcard symbol may retrieve word variants: doi chieu sang - ((thanh truong) or (thanh phuong)) va nang cong ((manh toan) or (van toan)) cao*.
