• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (((hieu van) OR (thien van)))) - van doanh cua nhung cong dan toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) or (((hieu van) OR (thien van)))) - van doanh cua nhung cong dan toan cao~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) or (((hieu van) OR (thien van)))) - van doanh cua nhung cong dan toan cao*.
