catalog filtering

[saturne75]

I have notice that more than 900 photos of my entire catalog seem not to belong to a collection.
So i would like to know how i can filter of my entire catalog the photos which are not in a collection.

Create a smart collection, where the criterion is

Collection name does not contain a e i o u y

Note that you need spaces between the letters "a e i o u y".
