• Performing a fuzzy search may retrieve terms with similar spellings: ((ho chieu) or (hoc thieu)) tinh - ((hanh trung) OR (manh trung)) cua khong cong tan van ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc thieu)) tinh - ((hanh trung) OR (manh trung)) cua khong cong tan van ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (hoc thieu)) tinh - ((hanh trung) OR (manh trung)) cua khong cong tan van ban".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (hoc thieu)) tinh - ((hanh trung) OR (manh trung)) cua khong cong tan van ban*.
