Or is it specifically for the search that you mentioned? It’s recommended. From https://wiki.openstreetmap.org/wiki/Key:waterway “If a waterway is named from its source to its destination, it's strongly suggested that all of its ways be placed in a waterway relation. Doing this allows Nominatim to group the ways together and return exactly one named result per named waterway that exists in OpenStreetMap.”
