• If you are trying to use Boolean operators, they must be ALL CAPS: ton thien hach - thanh ((trung cua) OR (trung cap)) nhung thong van ((toan cau) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ton thien hach - thanh ((trung cua) OR (trung cap)) nhung thong van ((toan cau) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: ton thien hach - thanh ((trung cua) OR (trung cap)) nhung thong van ((toan cau) or (toan cao))*.
