Hi Kim,
I looks like the 'IsEmpty' operator is missing on array types, and this is a bug.
However there is a small workaround:
In the index you use for your queries, you can add a new field (see FieldSetup.png), and then you use that field in your query together with the 'IsEmpty' operator. (see QuerySetup.png)
Now you should get a list of all the product, which are not in a group.
Best regards
Steffen
