Step 1.
if search 5731 with at least 1 letter, suggest api works fine.

Step 2.
if just search number, 5731, without any letter, it failed.
It should list all the address start with 5731.

Step 3.
This locator is use address layer as POINT ADDRESS role.

Step 4.
ArcPro locator, 5731 failed to list all address start with 5731

Step 5.
you have to type at least 1 letter after the number to show result,
but I do want to see how many address start with 5731, what street have 5731,

Step 6.
what if I make address layer as POI role, still failed search on address number,
If you search 5731, (address as poi role) will give you results based on combined POI name and address
but ( address as ADDRESS role) failed, nothing,

Step 7.
if type 5731 + b, both locator works fine.

Step 8.
what if I give address layer both ROLE, both POI role and ADDRESS role,
Step 9.
still does not search on address number, failed to list all address start with 5731
3090, should show all address start with 3090, instead of only 3090 slauson.

Step 10.
further improvement is add street address role ( street center line layer )

Step 11.
still failed to search only on address number

Step 12.
go further improvement by adding custom output field
After adding any custom output field, you will have to re-map these new added fields in FIELD MAPPING section above.

you will have to map any field is ok, but don't leave it blank, as None.

Step 13.
search 5731, first result comes from search address number.

Step 14.
try 2451, red box is result of all address start with 2451,
blue box is results of all business that has address start with 2451.

Step 15.
list all address that start with 2444, this is exactly I am trying to fix.

Step 16.
try 2425, blue box is address(include private + business) start with 2425,
yellow box is business only(no private), who;s address start with 2425.
Step 17.
Even ArcPro locator fixed, however, Arcgis REST api, suggest, still not search address number.
as long as your locator add any custom field, and map to any field is fine.
Then when you search address number only, suggest will popup

Step 18,
custom output field
