SolrJ解析MoreLikeThis查询结果

直接上代码：

/**
	 * 解析MoreLikeThis
	 * @author  likehua
	 * */
	public List<SolrDocument>  parseMoreLikeThis(QueryResponse response){
		List<SolrDocument> lst=new ArrayList<SolrDocument>();
		SimpleOrderedMap res= (SimpleOrderedMap) response.getResponse().get("moreLikeThis");
		for(int i=0;i<res.size();i++){
			Object o=res.getVal(i);
			if(o instanceof SolrDocumentList){
				SolrDocumentList items=(SolrDocumentList) o;
				for(SolrDocument d:items){
					if(d!=null){
						lst.add(d);
					}
				}
			}
		}
		return lst;
	}
	/**
