solr+solrJ facet.pivot 用法实例

1、要实现的功能

          

2、索引中字段

      

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

4、solr结果

              "value":"BB霜",
              "count":2}]}]}}}

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());
			}
		}

	}
