• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky tang van hoi. hieu ve cam xuc ban ((thanh tai) OR (thanh toan)) ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky tang van hoi. hieu ve cam xuc ban ((thanh tai) OR (thanh toan)) ((cua tre) or (cuu tre))".
