• Performing a fuzzy search may retrieve terms with similar spellings: ((thu sach) or (te sach)) y lang xa hoi. thien van chat duc va ((danh thin) OR (canh thin)) dua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (te sach)) y lang xa hoi. thien van chat duc va ((danh thin) OR (canh thin)) dua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) or (te sach)) y lang xa hoi. thien van chat duc va ((danh thin) OR (canh thin)) dua tre".
• Adding a wildcard symbol may retrieve word variants: ((thu sach) or (te sach)) y lang xa hoi. thien van chat duc va ((danh thin) OR (canh thin)) dua tre*.
