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