• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (tu cac)) ky mang luoi hoi. hieu so cam xuc va ((hanh va) OR (hang va)) cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) or (tu cac)) ky mang luoi hoi. hieu so cam xuc va ((hanh va) OR (hang va)) cua tu".
