In the database it does. That's what a relational database is. If the
API can't tell you, that's an easy problem to fix. Anyway, that's not
necessarily relevant as most of the time you will approach the problem
from the other end - i.e. find me number 27, The Avenue, so you download
the way "The Avenue" and all its segments, then you search for number 27.
