thuat hung » thuat dung, thuat ung, thuat xung
hung cong » nhung cong, hung cuong, phung cong
ho chieu » theo chieu, hoc thieu, doi chieu

• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - hanh chinh thuat hung cong san ((((toan ban) OR (doanh tai))) OR (toan cao))~.
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - hanh chinh thuat hung cong san ((((toan ban) or (doanh tai))) or (toan cao))*.
