Who is app discovery a problem for?

App developers, particularly small/indie/hobbyist developers like to complain about the challenges of having people discover their apps.

Yes, there are lots of challenges and problems with the way app stores and search work but how big are these issues?

Do real people have difficulty finding the apps they’re looking for? Both when looking for specific apps and for apps which perform specific functions.

Do non-developers see problems with store search results?

These are the important questions that I haven’t seen answers for. The only way to answer these questions would be with extensive research or the data that only stores have. Not matter what developers may think of the store and search results, these are the questions that matter.
