• If you are trying to use Boolean operators, they must be ALL CAPS: nhu ((hien sang) OR (khien bang)) - hanh chinh ((qua dung) OR (cua dong)) cong dan toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nhu ((hien sang) OR (khien bang)) - hanh chinh ((qua dung) or (cua dong)) cong dan toan cao".
• Adding a wildcard symbol may retrieve word variants: nhu ((hien sang) OR (khien bang)) - hanh chinh ((qua dung) or (cua dong)) cong dan toan cao*.
