• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu cach) OR (su sach)) ky nang x hoi. hieu van cao suc va ((hanh vai) OR (hanh vi)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu cach) or (su sach)) ky nang x hoi. hieu van cao suc va ((hanh vai) OR (hanh vi)) cua te".
• Adding a wildcard symbol may retrieve word variants: ((tu cach) or (su sach)) ky nang x hoi. hieu van cao suc va ((hanh vai) OR (hanh vi)) cua te*.
