• Performing a fuzzy search may retrieve terms with similar spellings: (( tu sach che my gia ((dong thong) OR (nong thon)) tin ) or ( te sach nha o giai con hoang minh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach che my gia ((dong thong) OR (nong thon)) tin ) OR ( te sach nha o giai con hoang minh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach che my gia ((dong thong) OR (nong thon)) tin ) or ( te sach nha o giai con hoang minh ))".
• Adding a wildcard symbol may retrieve word variants: (( tu sach che my gia ((dong thong) OR (nong thon)) tin ) or ( te sach nha o giai con hoang minh ))*.
