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