Is there any possibility of having the search function also search added member notes associated with verses of the standard works ( or all other works on Gospel Library)?
Searching verses based on notes is a good idea. The best way to send suggestions is via the in-app feedback, as the developers don't visit the forum frequently, and neither do the people who set priorities for church apps and sites (the forum is mainly user-to-user support and discussion).

This functionality exists in the gospel library 2.5 app (from years ago). I have both apps installed on my device just so that I can use this feature. Not sure why they took it away and haven't brought it back. It's a much needed feature.
