• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sac ky) OR (cac ky)) hang tai hoi. hieu va cham luc va tinh loi ((cua triet) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sac ky) OR (cac ky)) hang tai hoi. hieu va cham luc va tinh loi ((cua triet) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: su ((sac ky) OR (cac ky)) hang tai hoi. hieu va cham luc va tinh loi ((cua triet) or (cua te))*.
