People do, people are intelligent. Software does not. Software that searches for addresses needs to know how to interpolate (does that city use even/odd or left-up/right-down or house-numbers running around the block or whatever?), that 5A is near 5, all the places where a house cannot possible be, ... Given only a few house-numbers at intersections even people get it wrong quite often if they are used to other numbering-schemas then the one used there. This is a very, very complex thing to do once you think about it and it is still very hard to get it right even with the Karlsruhe Schema.
