The search engine for this mind map is in works and will essentially do what you have described. User types a query and it will jump to the correct place in the mind map.
If you want to help create it, please do. There is a slack group for the project.

A search function would be nice, e.g. if I search for rock climbing it would display something like
health->physical->fitness->rock climbing
