SQL index_description。 非丛集位于INDEXS / PRIMARY

Question

When I select a Table in Microsoft SQL Server Management Studio and hit "Alt+F1".

I see in 2 different nonclusetered indexes with different descriptions: nonclustered located on INDEXES nonclustered located on PRIMARY.

I do not expect it to be any different, can anyone explain what is the difference between these?

Answer 1

This is the name of the filegroup or partition scheme that the index is created on.
