• If you are trying to use Boolean operators, they must be ALL CAPS: thien hieu lang - ((canh manh) OR (lanh manh)) cua thong thong van ((tuan tap) OR (toan tai))~.
• Adding a wildcard symbol may retrieve word variants: thien hieu lang - ((canh manh) or (lanh manh)) cua thong thong van ((tuan tap) or (toan tai))*.
