• If you are trying to use Boolean operators, they must be ALL CAPS: su cac ((ky long) OR (ky trong)) ha hoi. hieu va cam ((luc va) OR (duc va)) hanh vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su cac ((ky long) OR (ky trong)) ha hoi. hieu va cam ((luc va) or (duc va)) hanh vi cua triet".
• Adding a wildcard symbol may retrieve word variants: su cac ((ky long) OR (ky trong)) ha hoi. hieu va cam ((luc va) or (duc va)) hanh vi cua triet*.
