• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) tu ((dong ha) OR (dong va)) hoi. hieu va cam xuc va doanh bat cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (thu sach)) tu ((dong ha) OR (dong va)) hoi. hieu va cam xuc va doanh bat cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (thu sach)) tu ((dong ha) OR (dong va)) hoi. hieu va cam xuc va doanh bat cua tre*.
