• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sang - canh tranh cua ((nhung thong) OR (nhung chong)) ((minh van) OR (vinh van)) ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sang - canh tranh cua ((nhung thong) OR (nhung chong)) ((minh van) or (vinh van)) ban~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sang - canh tranh cua ((nhung thong) OR (nhung chong)) ((minh van) or (vinh van)) ban*.
