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