• Performing a fuzzy search may retrieve terms with similar spellings: (( tu sach ((ha ke) OR (ha le)) giao cong thong tin ) or ( te sach nha xe gioi cau cong minh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach ((ha ke) OR (ha le)) giao cong thong tin ) OR ( te sach nha xe gioi cau cong minh ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach ((ha ke) OR (ha le)) giao cong thong tin ) or ( te sach nha xe gioi cau cong minh ))*".
