solr+solrJfacet.pivot用法实例

5、solrJ实现

	public   List  getTypeTree(Integer type,String name) throws SolrServerException{
		SolrServer solrServer = SolrServerManger.getInstance();
        SolrQuery sQuery = new SolrQuery();
        List types=new ArrayList();
            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> namedList = response.getFacetPivot();
            if(namedList != null){
                List pivotList = null;
                for(int i=0;i fieldList = pivot.getPivot();
                            if(fieldList != null){
                               List typeThrees=new ArrayList();
                                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 types=getTypeTree(2, "123");
		for(SearchType t:types){
			System.err.println(t.getName()+"===========");
			for(SearchType tt:t.getSubTypes()){
				System.err.println("   ---"+tt.getName());
			}
		}

	}

7、测试结果
