• If you are trying to use Boolean operators, they must be ALL CAPS: cao cho xanh - hanh hang cua ((nhung cong) OR (hang cong)) dan ((toan tai) OR (toan cao))~.
• Adding a wildcard symbol may retrieve word variants: cao cho xanh - hanh hang cua ((nhung cong) or (hang cong)) dan ((toan tai) or (toan cao))*.
