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