With "a" and without "a" in the indicative and subjective clausal adjectives

Hola Todos! Hi all. I have a question about  [El indicativo y el subjuntivo en cláusulas adjetivales]  


In the following sentences, I am curious why when the a is present, the verb vivir is in indicative form, and when a is absent, the verb vivir is conjugated in subjunctive form.

Estoy confuso, en los siguientes frases - que significa el a porque el verbo cambió a subjuntivo ... porque sin el "a" el verbo cambió a subjuntivo?


 "Buscan a un médico que vive aquí"


"Buscan un médico que viva aquí"

With the subjunctive, we’re looking for any doctor who may happen to live here. It’s hypothetical, so there is no real concrete doctor — no real person.

With the indicative, we are looking for a specific doctor that we know lives here. There is a real, concrete doctor.

The first sentence implies that they are looking for a doctor that lives around here. Meaning they currently reside in the area.

The second sentence implies that they are looking for a doctor/medic that will live/reside in the area.

Hi Phil! Thanks so much! I think I understand that part about the incertidumbre, but I am focusing know the phrase alludes to that based on the presence or absence of "a". Maybe it is really obvious, but I am still lost on why the "a" indicates existence, whereas without the "a", (the only difference in the sentences that I see) it indicates the unknown. Thanks again!
