Find or search are still in their infancy of development. In Damus you can search by npub and not much more.

In the other hand the Iris app has a more flexible way to find people.

I use it solely to that purpose, everything else I use Damus.

You can always peak others profile followers and follow from there.

For example: go to my profile and hit my following list, from there you will see who am i following and follow them.
