• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ly van cay phoi. hieu ((((ve cam) OR (ve cham))) OR (vien cac)) duc va khanh dinh cu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ly van cay phoi. hieu ((((ve cam) OR (ve cham))) or (vien cac)) duc va khanh dinh cu tre".
• Adding a wildcard symbol may retrieve word variants: su sach ly van cay phoi. hieu ((((ve cam) OR (ve cham))) or (vien cac)) duc va khanh dinh cu tre*.
