I'm not sure, but it looks like the object of the search is an Item, and you'd have to change it to Item Revision or use Referenced By under the Item to drill down to the Item Revision to get to the release status.
Sorry, I misunderstood. I missed the part where you want a more complex result: find all items with only revisions that are not released, and ignore all items that have one or more revisions with a releaase status or are in a release process. I'm not sure you can do that with a Query Builder query.
