• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty lang xa hoi. hieu ve cam xuc ((va thanh) OR (va tinh)) ((di cua) OR (dai cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty lang xa hoi. hieu ve cam xuc ((va thanh) or (va tinh)) ((di cua) OR (dai cua)) tre".
• Adding a wildcard symbol may retrieve word variants: te sach ty lang xa hoi. hieu ve cam xuc ((va thanh) or (va tinh)) ((di cua) OR (dai cua)) tre*.
