• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (lieu tinh)) - ((anh bang) OR (anh hoang)) va phuong cong tac than cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (lieu tinh)) - ((anh bang) OR (anh hoang)) va phuong cong tac than cao~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (lieu tinh)) - ((anh bang) OR (anh hoang)) va phuong cong tac than cao*.
