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