It also would mean that change occurred in version > range specified there - unfortunately I would not be able to test that. > This looks like a change in behaviour is not quite expected: now introducing > pf2 searches for documents that must have 'cat dog' phrase instead of just > boosting such documents. > Please let me know if more information is required. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
