一个lucene搜索高亮显示的例子。

//... Above, create documents with two fields, one with term vectors (tv) and one without (notv)  IndexSearcher searcher = new IndexSearcher(directory);  QueryParser parser = new QueryParser("notv", analyzer);  Query query = parser.parse("million");  TopDocs hits = searcher.search(query, 10);  SimpleHTMLFormatter htmlFormatter = new SimpleHTMLFormatter();  Highlighter highlighter = new Highlighter(htmlFormatter, new QueryScorer(query));  for (int i = 0; i < 10; i++) {    int id = hits.scoreDocs[i].doc;    Document doc = searcher.doc(id);    String text = doc.get("notv");    TokenStream tokenStream = TokenSources.getAnyTokenStream(searcher.getIndexReader(), id, "notv", analyzer);    TextFragment[] frag = highlighter.getBestTextFragments(tokenStream, text, false, 10);//highlighter.getBestFragments(tokenStream, text, 3, "...");    for (int j = 0; j < frag.length; j++) {      if ((frag[j] != null) && (frag[j].getScore() > 0)) {        System.out.println((frag[j].toString()));      }    }    //Term vector    text = doc.get("tv");    tokenStream = TokenSources.getAnyTokenStream(searcher.getIndexReader(), hits.scoreDocs[i].doc, "tv", analyzer);    frag = highlighter.getBestTextFragments(tokenStream, text, false, 10);    for (int j = 0; j < frag.length; j++) {      if ((frag[j] != null) && (frag[j].getScore() > 0)) {        System.out.println((frag[j].toString()));      }    }    System.out.println("-------------");  }

高亮显示顺便能对文本进行摘要提取。提取的摘要自动挂上高亮显示了。
