• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky sang ((ma hoi) OR (mai hoi)). hieu ve cham xuc van dinh ((di cua) OR (dai cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky sang ((ma hoi) OR (mai hoi)). hieu ve cham xuc van dinh ((di cua) or (dai cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: vu sach ky sang ((ma hoi) OR (mai hoi)). hieu ve cham xuc van dinh ((di cua) or (dai cua)) tre*.
