• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (te sach)) ky lang xa hoi. ((hieu va) OR (lieu va)) cham xuc va danh va su tien~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ky lang xa hoi. ((hieu va) OR (lieu va)) cham xuc va danh va su tien.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (te sach)) ky lang xa hoi. ((hieu va) OR (lieu va)) cham xuc va danh va su tien".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (te sach)) ky lang xa hoi. ((hieu va) OR (lieu va)) cham xuc va danh va su tien*.
