I have similar question: even if I add "--names-only" to the request like:

apt search --names-only bind

I received very long list inadequate results consisting of, among others, e.g.:

[...]elpa-bind-chord/jammy[...]
gir1.2-keybinder-3.0/jammy [...]
libbind-config-parser-perl/jammy[...]

19 pages... I don't get why. Looking for the explanation.
