What does "nose breath" mean?

What does the following mean? >You should not try to find the point where the moving air strokes the nostrils, but keep your focus at the nose breath. This comes from the followingpage that was linked to from another person: http://mahamevnawa.lk/ananda-sutta-leading-to-awakening/ I'm really not sure what they mean by "the nose breath". I generally have trouble with focusing anywhere near the nose. I can feel some coolness when breathing in, but I can feel nothing on the way out. I have tried for years and it has never become easier. That is why I focus on the abdomen as in the Mahasi style, but I still would like to know what this article means. Can you please explain to me what "nose breath" means?
