Solr的分组参数group.format =简单不适用于我

Question

我正在对solr查询结果进行分组，因此它分为多个组。要将所有这些组的结果合并到一个列表中，我正在使用"group.format=simple"。但是我认为它没有用。有人可以帮我解决这个问题，或者提供一个样本来说明如果"group.format=simple"在起作用的情况。请帮助

Solr查询：

http://localhost:8983/solr/core/select?q=((value1：“ solr search”）^ 10 OR（value1：solr and value1：search）^ 9）OR（value1：solr OR value1：search）＆fl = id，score＆group.limit = 5＆group = true＆group .query =（value1：“ solr search”）＆group.query =（（value1：solr AND value1：search）-（value1：“ solr search”））＆group.query =（（value1：solr OR value1：search）- （value1：“ solr search”）-（value1：solr AND value1：search））＆group.format = simple＆group.sort = plan desc＆wt = json
