• Performing a fuzzy search may retrieve terms with similar spellings: doc ((hieu manh) OR (hieu nganh)) - hanh trang cua cong dong dang ((hanh cat) or (hanh cham))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((hieu manh) OR (hieu nganh)) - hanh trang cua cong dong dang ((hanh cat) OR (hanh cham))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((hieu manh) OR (hieu nganh)) - hanh trang cua cong dong dang ((hanh cat) or (hanh cham))*".
