I have a number of Notebooks and assorted Stacks. This AM I was looking for a specific note in a folder I have called smoothie. I picked up my iPhone searched for Pumpkin and it found a Note titled Pumpkin Spice smoothie. I knew I had others. I then went to my lap top and searched all notes and it showed the one I was looking for called Protein Pumpkin smoothie. I went back to my iPhone navigated to the stack called smoothie and found the one I was looking for. So the defect I am seeing is Search on iOS all notes that contain Pumpkin does not display all occurrences . The Search on a Mac does.
