• If you are trying to use Boolean operators, they must be ALL CAPS: ((su thai) OR (su tai)) cao tang xa hoi. hieu ve ((cam duc) OR (pham duc)) va khanh thang cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su thai) or (su tai)) cao tang xa hoi. hieu ve ((cam duc) OR (pham duc)) va khanh thang cua te~".
• Adding a wildcard symbol may retrieve word variants: ((su thai) or (su tai)) cao tang xa hoi. hieu ve ((cam duc) OR (pham duc)) va khanh thang cua te*.
