• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (thu sach)) ky nang x hoi. hieu van cau xuc va ((nhan tai) OR (hang tai)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (thu sach)) ky nang x hoi. hieu van cau xuc va ((nhan tai) OR (hang tai)) cua te".
• Adding a wildcard symbol may retrieve word variants: ((te sach) or (thu sach)) ky nang x hoi. hieu van cau xuc va ((nhan tai) OR (hang tai)) cua te*.
