Why does `flatpak search .` return way more results than the API

1

I’m trying to figure out why flatpak search is giving more results than the flathub API:

# flatpak search . --columns=application,remotes | grep flathub | sort | uniq | wc -l
4018
# curl --silent --location https://flathub.org/api/v2/stats | jq .totals.number_of_apps
3554

Might be related to EOL apps or baseapp and plugins?
