• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ly nang xa hoi. hieu qua cam xuc ((va danh) OR (((van thanh) OR (van tuan)))) vai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ly nang xa hoi. hieu qua cam xuc ((va danh) or (((van thanh) OR (van tuan)))) vai cua te".
• Adding a wildcard symbol may retrieve word variants: thu sach ly nang xa hoi. hieu qua cam xuc ((va danh) or (((van thanh) OR (van tuan)))) vai cua te*.
