使用 Lucene 突出显示结果

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);

我在尝试获得突出显示的结果时遇到此错误：

无法在服务模块加载器的模块“deployment.dev-1.0.war:main”中定义类 org.apache.lucene.search.highlight.TermVectorLeafReader：java.lang.VerifyError：

当使用与预期的 Apache Lucene 版本不兼容的 Highlighter 版本时，您会得到这样的 VerifyError。

验证您的应用服务器正在使用哪个版本的 Lucene，并获取匹配的荧光笔版本。
