Search for null objects

Hi,

I need to find all objects which doesn't have any categories.

At the moment I've tried something like this:

query = query.Filter(x => x.SearchCategories.IsNull().Match(true));

But it doesn't work. Is it possible to search for null values?

You should be able to use .Exists():

query = query.Filter(x => x.SearchCategories.Exists());

Thank you! It works beautifuly.

Ended using it like this:

query = query.Filter(x => !x.SearchCategories.Exists());
