• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chua) OR (cheo cua)) xang - ((anh dong) OR (anh hoang)) va dung tuong tac toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chua) OR (cheo cua)) xang - ((anh dong) or (anh hoang)) va dung tuong tac toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((theo chua) OR (cheo cua)) xang - ((anh dong) or (anh hoang)) va dung tuong tac toan ban*.
