How bubble handles conditions based on real-time searching

I have a condition to make a Button “Disabled” if the current “thing”'s name (the “thing” the user is trying to create with this button) is the already in the database.

(Only When: Do a search for “Contact”, constraint by Name = Parent things Name, count > 0)

How will bubble handle this? will bubble constantly keep searching the database and count it? and would such a background activity put strain on my app?
