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