The "summary" information is generated dynamically by summarizer like "summary-cn"  based on the "parse_text " stored  in segment.
When NutchBean receive a query , it will get a  document  list which match your query, then NutchBean can get segment name and document URL  through the document object. By using segment name and URL you can get the parse_text information of that page from the segment. Finally, the parse_text of this page will be sent to Summarizer, summarizer will generate snippet based on the parse text information for this page..
