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