• If you are trying to use Boolean operators, they must be ALL CAPS: cho ((chua xang) OR (chuc nang)) - hanh tang cua nhung cong san ((toan cau) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho ((chua xang) or (chuc nang)) - hanh tang cua nhung cong san ((toan cau) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: cho ((chua xang) or (chuc nang)) - hanh tang cua nhung cong san ((toan cau) OR (toan ban))*.
