• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sac ky) OR (sai ky)) lang xa hoi. hieu va tham ((luc va) OR (duc va)) hinh thai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sac ky) OR (sai ky)) lang xa hoi. hieu va tham ((luc va) or (duc va)) hinh thai cua triet".
• Adding a wildcard symbol may retrieve word variants: te ((sac ky) OR (sai ky)) lang xa hoi. hieu va tham ((luc va) or (duc va)) hinh thai cua triet*.
