I am trying to search within my notes (hadn't tried to before) and am finding that it seems I cannot. At one point it seems there was a search function available:

But this no longer seems to be the case. I've also gone back through the MP training manuals and see no reference to this, so I have a disappointing hunch this is not going to be happening for me. 
Thanks in advance.
