## 1、要实现的功能 ##

![Center][]

## 2、索引中字段 ##

![Center 1][]

## 3、solr搜索 ##

[http://\*\*\*\*/collection1/select?q=shop\_id:123&rows=1&wt=json&indent=true&facet=true&facet.pivot=p\_type\_name,type\_name][http_collection1_select_q_shop_id_123_rows_1_wt_json_indent_true_facet_true_facet.pivot_p_type_name_type_name]

## 4、solr结果 ##

## 5、solrJ实现 ##

public   List<SearchType>  getTypeTree(Integer type,String name) throws SolrServerException{
    		SolrServer solrServer = SolrServerManger.getInstance();
            SolrQuery sQuery = new SolrQuery();
            List<SearchType> types=new ArrayList<SearchType>();
                sQuery.setFacet(true);
                sQuery.add("facet.pivot", "p_type_name,type_name");        //根据这两维度来分组查询
                switch (type) {
    			case 1:
    				sQuery.setQuery("name:"+name);
    				break;
    			case 2:
    				sQuery.setQuery("shop_id:"+name);
    				break;
    			default:
    				sQuery.setQuery("*:*");
    				break;
    			}
                QueryResponse response = solrServer.query(sQuery);
                NamedList<List<PivotField>> namedList = response.getFacetPivot();
                if(namedList != null){
                    List<PivotField> pivotList = null;
                    for(int i=0;i<namedList.size();i++){
                        pivotList = namedList.getVal(i);
                        if(pivotList != null){
                            for(PivotField pivot:pivotList){
                            	SearchType typeTwo=new SearchType();
                            	typeTwo.setName(pivot.getValue().toString());
                                List<PivotField> fieldList = pivot.getPivot();
                                if(fieldList != null){
                                   List<SearchType> typeThrees=new ArrayList<SearchType>();
                                    for(PivotField field:fieldList){
                                    	 SearchType typeThree=new SearchType();
                                    	 typeThree.setName(field.getValue().toString());
                                    	 typeThrees.add(typeThree);
                                    }
                                    typeTwo.setSubTypes(typeThrees);
                                    types.add(typeTwo);
                                }
    
                            }
                        }
                    }
                }
            return types;
    	}

## 6、solrj测试代码 ##

public static void main(String  [] args) throws SolrServerException{
    		List<SearchType> types=getTypeTree(2, "123");
    		for(SearchType t:types){
    			System.err.println(t.getName()+"===========");
    			for(SearchType tt:t.getSubTypes()){
    				System.err.println("   ---"+tt.getName());
    			}
    		}
    
    	}
