• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu tinh) OR (chau tinh)) - anh tang cua nhung cong tan ((doanh tai) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu tinh) OR (chau tinh)) - anh tang cua nhung cong tan ((doanh tai) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu tinh) OR (chau tinh)) - anh tang cua nhung cong tan ((doanh tai) or (toan ban))*.
