vu sai » vu hai, vu san, vu dai
nam tu » nam thu, nam thuc
ve cua » le cua, de cua, te cua

• If you are trying to use Boolean operators, they must be ALL CAPS: vu sai ((ky lang) OR (ky nang)) xa hoi. hieu ve ((nam tu) OR (am thuc)) va thanh ve cua tu.
• Adding a wildcard symbol may retrieve word variants: vu sai ((ky lang) or (ky nang)) xa hoi. hieu ve ((nam tu) or (am thuc)) va thanh ve cua tu*.
