I think the question is when does the search feature show up on ANY maps. It seems Ms Jackie does not have the feature and was thinking it is on a specific map provider but from what I can see it is on the default game maps so would transfer to any of the map makers packs. That's why I linked in the last one from the Alla wikki so she could see the default game map they picture that shows the search feature.
IIUC, that search bar is just to search for matching map labels. If the mob isnt on your map already it wont find it.
