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