> Url field is indexed as Strore.YES , Index.TOKENIZED. We also need the untokenized version
of the url field in some contexts : 
> 1. For deleting duplicates by url (at search time). see NUTCH-455
> 2. For restricting the search to a certain url (may be used in the case of RSS search
where each entry in the Rss is added as a distinct document with (possibly) same url ) 
>    query-url extends FieldQueryFilter so: 
>     Query: url:http://www.apache.org/
>     Parsed: url:"http http-www http-www-apache www www-apache apache org"
>     Translated: +url:"http-http-www http-www-http-www-apache http-www-apache-www www-www-apache
www-apache apache org"
> 3. for accessing a document(s) in the search servers in the search servers. (using query
plugin)
> I suggest we add url as in index-basic and implement a query-url-untoken plugin. 
> doc.add(new Field("url", url.toString(), Field.Store.YES, Field.Index.TOKENIZED));
> doc.add(new Field("url_untoken", url.toString(), Field.Store.NO, Field.Index.UN_TOKENIZED));
