• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((thieu xanh) OR (hieu manh)) - ((hanh trang) or (hanh chinh)) cua thuong cong dan han tap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu xanh) OR (hieu manh)) - ((hanh trang) OR (hanh chinh)) cua thuong cong dan han tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) OR (hieu manh)) - ((hanh trang) or (hanh chinh)) cua thuong cong dan han tap*".
