• Performing a fuzzy search may retrieve terms with similar spellings: ((ho chieu) or (((hoc thieu) OR (hoc hien)))) tinh - hanh dinh thi nang cong dan thanh san~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (((hoc thieu) OR (hoc hien)))) tinh - hanh dinh thi nang cong dan thanh san*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (((hoc thieu) OR (hoc hien)))) tinh - hanh dinh thi nang cong dan thanh san*".
