• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ly ((hang xa) OR (hoang xa)) hoi. hieu du chat lua ((van hanh) or (van anh)) vi su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ly ((hang xa) OR (hoang xa)) hoi. hieu du chat lua ((van hanh) OR (van anh)) vi su triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ly ((hang xa) OR (hoang xa)) hoi. hieu du chat lua ((van hanh) or (van anh)) vi su triet".
• Adding a wildcard symbol may retrieve word variants: tu sach ly ((hang xa) OR (hoang xa)) hoi. hieu du chat lua ((van hanh) or (van anh)) vi su triet*.
