• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu xanh - ((ganh nang) OR (anh nang)) cua nhung cong vinh ((toan cao) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - ((ganh nang) OR (anh nang)) cua nhung cong vinh ((toan cao) or (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - ((ganh nang) OR (anh nang)) cua nhung cong vinh ((toan cao) or (toan tap))*.
