With another map, Address search is different.
Postal Codes is not a feature of this map, so "Enter postal Code" it's disabled and not shown on the screen.
Smart filtering is also disabled with this map and as I continue to tap on letters, the list of available cities is shown on the screen.
I believe it has to do with the \.System\SID folder and CNxxNT maps.
I think I found the answer to my question. The address entry style appears to be controlled by the locale and not by the firmware (but the maps may also control it too; my testing was only with NA maps).

I first found that by changing the locale from United States to Australia, I got the smart filtering style of address entry instead of the number pad.

Then I examined the locale.xml file in the .System folder and found that there are two types of address entry modes: "Standard" and "Enhanced." By default, the United States locale's address entry mode is "Enhanced". To test my theory, I edited the locale.xml file to change this to "Standard" for the United States. I then reset the unit's locale to the United States. I did an address entry and it did indeed do the smart filtering now.
