• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) or (((nhieu tang) OR (nhiet nang)))) - hanh tranh cua bang huong dan phan cac~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) or (((nhieu tang) OR (nhiet nang)))) - hanh tranh cua bang huong dan phan cac*.
