我正在对 solr 进行构面查询。这给了我构面及其每个项目的计数...但是现在我想对构面执行组查询。这使我根据组进行计数...

例子

下面是数据

Item1：耐克鞋（尺码：8,9,10） Item2：锐步鞋（尺码：8,9,10）

现在在这种情况下，我的品牌方面查询返回结果如下

  • 耐克：3

  • 锐步：3

我需要的结果是

  • 耐克：1
  • 锐步：1

问候

http://1XX.XXX.XXX.XXX:8080/solr/autocomplete/select?q=displayterm:new&wt=json&indent=true&q.op=and&fl=displayterm&group=true&group.field=displayterm

注意：&group=true&group.field=displayterm
此响应按 displayterm 分组
