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