• Performing a fuzzy search may retrieve terms with similar spellings: doc ((hieu manh) OR (dieu hanh)) - hanh tuong duong thuong luong van ((hanh cham) or (thanh cac))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((hieu manh) OR (dieu hanh)) - hanh tuong duong thuong luong van ((hanh cham) OR (thanh cac))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((hieu manh) OR (dieu hanh)) - hanh tuong duong thuong luong van ((hanh cham) or (thanh cac))*".
