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