• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach thu) OR (sach tham)) nang xa hoi. hieu va cham ((xuc va) OR (duc va)) hanh di cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach thu) OR (sach tham)) nang xa hoi. hieu va cham ((xuc va) or (duc va)) hanh di cua te".
