• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (toc sach)) thu ((hang x) OR (hoang xa)) hoi. hieu qua cam xuc va hang doi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (toc sach)) thu ((hang x) OR (hoang xa)) hoi. hieu qua cam xuc va hang doi cua te*".
