• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (thu sach)) v nang mai khoi. hieu va cam xuc van ((thanh de) OR (thanh ve)) cua quoc~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) v nang mai khoi. hieu va cam xuc van ((thanh de) OR (thanh ve)) cua quoc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (thu sach)) v nang mai khoi. hieu va cam xuc van ((thanh de) OR (thanh ve)) cua quoc".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (thu sach)) v nang mai khoi. hieu va cam xuc van ((thanh de) OR (thanh ve)) cua quoc*.
