How to search?

DK 8.7.0 appimage.

I'm trying to cleanup/reorganize my photos. Right now, I'm using the
album tab and using the filter tab interactively. I work with 1 album
at a time.

I trying to create a search that I can reuse. 

- all the image without a rating (picture properties: no problem)
- all the images without a flag (picture properties: no problem)

My problem is how to do?
- restrict the search just to the current album that is highlighted in
  the album tab
