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