by the way
I found date sortable by the code in MoreIndexingFilter.java @line 122
doc.add(new Field("date", dateString, Field.Store.NO,
Field.Index.UN_TOKENIZED));
and found sorting reversable by the code in search.jsp @line 105
String params = "&hitsPerPage="+hitsPerPage
+(sort==null ? "" : "&sort="+sort+(reverse?"&reverse=true":""));
I'm using nutch 0.9
