• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sang - ((hanh tang) OR (anh tang)) luan nhung phuong ((dan toan) OR (dan than)) ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sang - ((hanh tang) or (anh tang)) luan nhung phuong ((dan toan) OR (dan than)) ban~".
• Adding a wildcard symbol may retrieve word variants: theo chieu sang - ((hanh tang) or (anh tang)) luan nhung phuong ((dan toan) OR (dan than)) ban*.
