• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sac ky) OR (cac ky)) ((sang xa) OR (tang ma)) hoi. thien van pham duc va danh dau cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sac ky) OR (cac ky)) ((sang xa) or (tang ma)) hoi. thien van pham duc va danh dau cua tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sac ky) OR (cac ky)) ((sang xa) or (tang ma)) hoi. thien van pham duc va danh dau cua tre*.
