• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky dong mau hoi. hieu ve cam luc ((va thanh) OR (gia thanh)) ((hai cua) OR (dai cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky dong mau hoi. hieu ve cam luc ((va thanh) or (gia thanh)) ((hai cua) OR (dai cua)) tre*".
