使用Lucene

Question

 QueryScorer queryScorer = new QueryScorer(query, "title"); 
     Fragmenter fragmenter = new SimpleSpanFragmenter(queryScorer); 

     Highlighter highlighter = new Highlighter(queryScorer); // Set the best scorer fragments 
     highlighter.setTextFragmenter(fragmenter); // Set fragment to highlight    

     SearchFactory searchFactory = fullTextEntityManager.getSearchFactory(); 
     IndexReader indexReader = searchFactory.getIndexReaderAccessor().open(SearchResult.class);   
     indexSearcher = new IndexSearcher(indexReader); 
     // STEP C 
     System.out.println(""); 
     ScoreDoc scoreDocs[] = indexSearcher.search(query, 20).scoreDocs; 
     for (ScoreDoc scoreDoc : scoreDocs) { 
      Document document = indexSearcher.doc(scoreDoc.doc); 
      String title = document.get("title"); 
      TokenStream tokenStream = analyzer.tokenStream("title", new StringReader(title)); 
      LOG.info(String.format("TEXTE BRUT: %s", title)); 
      String fragment = highlighter.getBestFragments(tokenStream, title, 3, "..."); 
      LOG.log(Level.INFO, "--------- FRAGMENT search : ", fragment); 

突出成績我有這樣的錯誤，我試圖讓在突出顯示的結果：

當使用與預期版本的Apache Lucene不兼容的Highlighter版本時，您將獲得這樣的VerifyError。
