nutch 0.9二次开发--搜索结果高亮

方法1.将 org.apache.nutch.searcher.Summary 第107行 代码 修改为：

public String toString() {
    StringBuffer buffer = new StringBuffer();
    for (int i = 0; i < fragments.size(); i++) {
      buffer.append(fragments.get(i));
    }
    return "<span style='color:red'>" + buffer.toString()+ "</span>";
}

方法2. Hits hits = bean.search(query, 10);

HitDetails detail=bean.getDetails(hits.getHit(i));
Summary summaries = bean.getSummary(detail, query);

String content=summaries.toHtml(true);  //这样得到高亮显示的HTML
