Laur, here's what I do. I first limit my search to one of my categories. I use type of plant, you use garden bed. So, limit your search to your Knick Knack garden and update the view. Then do a Control-F (find) and in the little box that comes up, type in e.g., Hemer to find all your daylillies in this bed. At the bottom of the screen a small box appears showing how many 'hits' there are and you can use the arrow buttons to scroll from one to the next.
I found that searching the whole list is a bit cumbersome because it only searches the first page (first 500 entries). Just when I think I've somehow lost data, I remember to go to page 2. So now I do an initial limit by choosing (in the above example) my Perennial category.
Hope I've been clear and it works for you.
