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