• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky nang ma hoi. hieu va ((cao duc) OR (giao duc)) va thanh ve ((cua tre) OR (cua te))".
• Adding a wildcard symbol may retrieve word variants: thu sac ky nang ma hoi. hieu va ((cao duc) OR (giao duc)) va thanh ve ((cua tre) OR (cua te))*.
