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