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

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());
}
}
}
7、测试结果
