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