• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty hang xay hoi. hieu va cam xuc ((va thanh) OR (ban thanh)) ((vai cua) OR (dai cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty hang xay hoi. hieu va cam xuc ((va thanh) OR (ban thanh)) ((vai cua) or (dai cua)) tre*".
