I have just received an update from Waze staff about this problem:
As for the problem - the main issue is the fact we are using an external source for resolving addresses. This is something we must do, since a lot of the house addresses are not known to us.
However, this causes exactly what you've described - cases where the address exists in Waze, but the search does not return it.
We are working on a new search mechanism that will solve this issue, however, it is a large effort and not an easy fix we can deploy. So I believe it will still take a couple of months until we fully deploy the new search mechanism. Hopefully, we will be able to start testing it soon and see that it indeed solves the problem you mentioned.
