• Performing a fuzzy search may retrieve terms with similar spellings: ((((tu san) OR (thu san))) or (tu can)) ky lang xa hoi. hieu van cau duc va thanh vi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((tu san) OR (thu san))) OR (tu can)) ky lang xa hoi. hieu van cau duc va thanh vi cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((tu san) OR (thu san))) or (tu can)) ky lang xa hoi. hieu van cau duc va thanh vi cuu tre*".
