• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (nhieu tang)) - hanh tranh cua tong thong ((ban than) OR (ban hang)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) or (nhieu tang)) - hanh tranh cua tong thong ((ban than) OR (ban hang)) cao~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) or (nhieu tang)) - hanh tranh cua tong thong ((ban than) OR (ban hang)) cao*.
