• Performing a fuzzy search may retrieve terms with similar spellings: ((hoc thieu) or (theo chieu)) xanh - hanh tinh cua dong cong dan ((toan cao) OR (toan ban))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (theo chieu)) xanh - hanh tinh cua dong cong dan ((toan cao) OR (toan ban))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (theo chieu)) xanh - hanh tinh cua dong cong dan ((toan cao) OR (toan ban))*".
