• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y dang thai hoi. hieu ((doc chat) OR (hop chat)) va van anh dai ((cua te) OR (cua su))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y dang thai hoi. hieu ((doc chat) OR (hop chat)) va van anh dai ((cua te) or (cua su))~".
• Adding a wildcard symbol may retrieve word variants: tu sach y dang thai hoi. hieu ((doc chat) OR (hop chat)) va van anh dai ((cua te) or (cua su))*.
