• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty lang xa hoi. hieu van anh toc va doan van ((cua te) OR (((cua cu) OR (cua su))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty lang xa hoi. hieu van anh toc va doan van ((cua te) or (((cua cu) OR (cua su))))~".
• Adding a wildcard symbol may retrieve word variants: te sach ty lang xa hoi. hieu van anh toc va doan van ((cua te) or (((cua cu) OR (cua su))))*.
