"Seen" means "had eyes on". It does not usually mean "found".
Student or Learner
John: Have you seen my daughter?
Me: Yes, I have seen your daughter.
If "seen" means "found". Is Present Perfect here used to describe the result of action which happened in past? What is the past action then?
"I have had eyes on your daughter" means that you are attracted to her, and probably not the way you'd say this to a father.
The past action is having seen the daughter.
You can say, "Have you seen my daughter?" if you are looking for her. The appropriate answer (if the hearer has seen her) is something like "Yes, I saw her in the mall about 15 minutes ago."
'I have seen your daughter. It was decades ago, when she was a baby.'
Is it possible?
