I don't know what causes this, but a workaround that usually works is to remove and re-download the book. To remove the book, go to Library > Scriptures, then long-press on "Book of Mormon" and choose Remove. Then tap it again to re-download it. Give the app a minute or two to re-index the book for search (it shouldn't take too long). Then, you should be able to get search results in the Book of Mormon again. The same process should work for other books that may not show up in search results.
