• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((nhiet nang) OR (((chieu sang) OR (hieu lang)))) - nhanh thanh va tong cong dang toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((nhiet nang) or (((chieu sang) OR (hieu lang)))) - nhanh thanh va tong cong dang toan tap~".
• Adding a wildcard symbol may retrieve word variants: ho ((nhiet nang) or (((chieu sang) OR (hieu lang)))) - nhanh thanh va tong cong dang toan tap*.
