Sql server 与sql server 2012中的其他相同数据库相比，用于查找一个数据库中缺少的索引的脚本

我有两个数据库，分别是test1和test2，两者都是相同的，即都有相同的表和相同的名称。但是test1在表上有一些索引，而这些索引在test2数据库中缺失。与sql server 2012中的test1数据库相比，如何编写脚本来查找test2数据库中缺失的索引。我尝试了下面的脚本，但它显示了所有索引。但我只希望在中缺少索引与test1数据库相比，test2数据库

select *
  from
       (select s1.name           as SchemaName
              ,t1.name           as TableName

              from test1.sys.schemas s1

并在

末尾添加，其中r2.IndexName为null
