• Performing a fuzzy search may retrieve terms with similar spellings: (( tu sach ca me gioi con dong tin ) or ( tu sach che ((me nguoi) OR (ma nguoi)) cau thong tienh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach ca me gioi con dong tin ) OR ( tu sach che ((me nguoi) OR (ma nguoi)) cau thong tienh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach ca me gioi con dong tin ) or ( tu sach che ((me nguoi) OR (ma nguoi)) cau thong tienh ))".
• Adding a wildcard symbol may retrieve word variants: (( tu sach ca me gioi con dong tin ) or ( tu sach che ((me nguoi) OR (ma nguoi)) cau thong tienh ))*.
