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;
	}
	/**
	 * MoreLikeThis查询
	 * @author  likehua
	 * */
	public  List<Index> getLikeResult(String param){
		List<Index> likes = new ArrayList<Index>();
		String strQuery = "";
		if(param != null && param.length()>0){
			Pattern pt = Pattern.compile("\\s+");
			Matcher mc = pt.matcher(param.trim());
			String strParam = mc.replaceAll(","); 
			strQuery = "geo_name:"+strParam+ " OR geo_summary:"+strParam;		
    	}else{
    		strQuery = "*:*";
    	}
			
		try {
			SolrQuery likeQuery = new SolrQuery(strQuery);
			likeQuery.setParam("mlt", "true").setParam("mlt.fl", "geo_name,geo_summary").setParam("mlt.count", "1");						
			QueryResponse response = SolrServer.getServer().query(likeQuery);
	    	List<SolrDocument> responseList=parseMoreLikeThis(response);
			//SimpleOrderedMap res=  (SimpleOrderedMap) response.getResponse().get("moreLikeThis");
			for(SolrDocument sd:responseList) {
				String name = (String)sd.getFieldValue("geo_name");
				Index index = new Index();
				index.setLike(name);
				likes.add(index);
			}
		} catch (SolrServerException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}	
		return likes;		
	}
