• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sac ky) OR (sai ky)) nang ma hoi. hieu ((van cam) OR (van cau)) luc va lang doi cu tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sac ky) OR (sai ky)) nang ma hoi. hieu ((van cam) or (van cau)) luc va lang doi cu tren".
