查询:高亮还有问题在找,找到后补充

   public Page<UserVo> getShow(String name) {

//        highlightBuilder.requireFieldMatch(true);     //如果要多个字段高亮,这项要为false

        //下面这两项,如果你要高亮如文字内容等有很多字的字段,必须配置,不然会导致高亮不全,文章内容缺失等
//        highlightBuilder.fragmentSize(800000); //最大高亮分片数
//        highlightBuilder.numOfFragments(0); //从第一个分片获取高亮片段
