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