thanh vi » thanh va, thanh ve, nhanh vi
cao hoi » cau hoi, co hoi, cao hoc
luc van » luoc van, duc van, luc va
luu van » cuu van, luan van, luu hanh

• If you are trying to use Boolean operators, they must be ALL CAPS: ke san ky nang cao hoi. thien van nam ((luc van) OR (luu van)) ((thanh vi) OR (hanh vi)) cua triet.
• Adding a wildcard symbol may retrieve word variants: ke san ky nang cao hoi. thien van nam ((luc van) or (luu van)) ((thanh vi) or (hanh vi)) cua triet*.
