• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) thu nang xa hoi. hieu ve chat ((tuc ban) OR (tu ban)) thanh tai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (su sach)) thu nang xa hoi. hieu ve chat ((tuc ban) OR (tu ban)) thanh tai cua triet".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (su sach)) thu nang xa hoi. hieu ve chat ((tuc ban) OR (tu ban)) thanh tai cua triet*.
