• Performing a fuzzy search may retrieve terms with similar spellings: (( te sach cha me gioi van dong tin ) or ( toc sach ha me ((gioi cau) OR (gioi cam)) cong tan ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( te sach cha me gioi van dong tin ) OR ( toc sach ha me ((gioi cau) OR (gioi cam)) cong tan ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te sach cha me gioi van dong tin ) or ( toc sach ha me ((gioi cau) OR (gioi cam)) cong tan ))*".
