• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky tang ma hoi. hieu ve ((cam duc) OR (cam xuc)) ban ((hang hai) OR (thanh hai)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky tang ma hoi. hieu ve ((cam duc) or (cam xuc)) ban ((hang hai) OR (thanh hai)) cua te".
• Adding a wildcard symbol may retrieve word variants: su sac ky tang ma hoi. hieu ve ((cam duc) or (cam xuc)) ban ((hang hai) OR (thanh hai)) cua te*.
