• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky mang lai hoi. hieu so chat luc va danh ((vai cua) OR (((lai cua) OR (dai cua)))) te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky mang lai hoi. hieu so chat luc va danh ((vai cua) or (((lai cua) OR (dai cua)))) te~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky mang lai hoi. hieu so chat luc va danh ((vai cua) or (((lai cua) OR (dai cua)))) te*.
