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