Very frustrated by the search feature in LDS gospel library.
Used to list scriptures in each volume of scripture, OR, NT, BoM, D&C
Now there is no difference between the ALL and the Scripture feature.
The best way to search in Gospel Library if you know what section it's in is to go to that section, then perform the search. For example, if you only want results from the scriptures, go to the Scriptures section, tap search, type the word or phrase you want to search, then tap the search suggestion right below the search box that says "Find x in Scriptures." You can do something similar inside a book (like the Book of Mormon), a sub-book (like 1 Nephi), or a single chapter.
