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