Lucene Plugin not indexing new articles

Hi,

in OJS 3.3.0, rebuilding the index works while when publishing a new article it is not added to the index.

When I add the journal ID as a second parameter in the following line:

pkp/lucene/blob/stable-3_3_0/LucenePlugin.inc.php#L665


      
          		// and let the Solr server initiate indexing.
          		if ($this->getSetting(CONTEXT_SITE, 'pullIndexing')) return true;
          
          
		// If the plugin is configured to push changes to the
          		// server then we'll now batch-update all articles that
          		// changed since the last update. We use a batch size of 5
          		// for online index updates to limit the time a request may be
          		// locked in case a race condition with a large index update
          		// occurs.
          		$solrWebService = $this->getSolrWebService();
          		$result = $solrWebService->pushChangedArticles(5);
          		if (is_null($result)) {
          			$this->_informTechAdmin($solrWebService->getServiceMessage());
          		}
          
          
		return true;
          	}
          
          
	/**
          	 * @see ArticleSearchIndex::rebuildIndex()
          	 */

the article is indexed after publication.

There are two other things I noticed (articleId):

github.com

pkp/lucene/blob/stable-3_3_0/LucenePlugin.inc.php#L609


      
          
          
		return true;
          	}
          
          
	/**
          	 * @see ArticleSearchIndex::submissionFileChanged()
          	 */
          	function callbackSubmissionFileChanged($hookName, $params) {
          		assert($hookName == 'ArticleSearchIndex::submissionFileChanged');
          		list($articleId, $type, $fileId) = $params;
          		$this->_solrWebService->setArticleStatus($article->getId());
          		// in OJS core in many cases callbackArticleChangesFinished is not called.
          		// So we call it ourselves, it won't do anything is pull-indexing is active
          		$this->callbackArticleChangesFinished(null, null);
          
          
		return true;
          	}
          
          
	/**
          	 * @see ArticleSearchIndex::submissionFileDeleted()
          	 */

github.com

pkp/lucene/blob/stable-3_3_0/LucenePlugin.inc.php#L623


      
          
          
		return true;
          	}
          
          
	/**
          	 * @see ArticleSearchIndex::submissionFileDeleted()
          	 */
          	function callbackSubmissionFileDeleted($hookName, $params) {
          		assert($hookName == 'ArticleSearchIndex::submissionFileDeleted');
          		list($articleId, $type, $assocId) = $params;
          		$this->_solrWebService->setArticleStatus($article->getId());
          
          
		return true;
          	}
          
          
	/**
          	 * @see ArticleSearchIndex::articleDeleted()
          	 */
          	function callbackArticleDeleted($hookName, $params) {
          		assert($hookName == 'ArticleSearchIndex::articleDeleted');
          		list($articleId) = $params;
