It is not possible to search the content of a Prose article with the CTRL+K global search or the Advanced Search in the articles manager. As I am writing longer prose articles it makes it difficult to find a specific word across each chapter.
As a result, prose articles are the only template where the main text cannot be searched globally.
honestly it'd be nice if the default search bar had a wiki style thing where if it didn't find a specific article it'd search page content as well and list the possibilities on its own page.
I am always for improving the search. I believe all text boxes should be searchable.
