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.
