[jira] Updated: (NUTCH-479) Support for OR queries

["Robert Buccigrossi (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/NUTCH-479?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Robert Buccigrossi updated NUTCH-479:
-------------------------------------

    Attachment: nutch_0.9_OR.patch

The problem with the 2007 patch is that it translates:

  brain apples OR oranges
to
 +brain +apples oranges

The included patch translates the phrase to

 +brain apples oranges

(specifically it makes the previous clause non-mandatory, which I believe is the preferred behavior).

I hope this helps.
