Index url field untokenized
---------------------------
Key: NUTCH-541
URL: https://issues.apache.org/jira/browse/NUTCH-541
Project: Nutch
Issue Type: New Feature
Components: indexer, searcher
Affects Versions: 1.0.0
Reporter: Enis Soztutar
Assignee: Enis Soztutar
Fix For: 1.0.0
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));
