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