• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chua xang) OR ((chuc OR chu) nang)) - anh bang va nhung cong manh ((toan cau) OR (toan cao)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chua xang) or ((chuc or chu) nang)) - anh bang va nhung cong manh ((toan cau) OR (toan cao))".
• Adding a wildcard symbol may retrieve word variants: theo ((chua xang) or ((chuc or chu) nang)) - anh bang va nhung cong manh ((toan cau) OR (toan cao))*.
