Select references that are different between two groups

I have two groups with many references. The first has 1500 and the second has 2500. In the second group there are included all references of the first group and in addition 1000 more. I would like to know which one are these 1000, that are only in the second group.

Thank you in advance!

So you can use the Combination Group option:

Creating a Combination Group

To create a combination group:

  1. From the Groups panel, select Create from Groups to display the Create from Groups dialog.

  2. Enter a name for the combination group.

  3. In the fields under the Include References heading, select up to 10 custom and/or smart groups to use as  your search criteria.

  4. Use AND, OR, NOT to include or exclude custom and/or smart groups in your combined group set.

  5. You can also use the Add (+) and Remove (-) buttons to manage which groups you want to include in and/or remove from  your combined group set

So you can do Group 2 Not Group 1 and it would tell you what is unique in Group 2.
