Step 1
ArcPro locator, 5731 failed to list all address start with 5731

Step 2.
at least 1 letter after the number to make it works,
but I do want to see how many address start with 5731, what street have 5731,

Step 3.
quick fix, must have ADDRESS ROLE, must have at least one custom output field map to any field.

Step 4.
Only have POI role, even have one custom output fields, Does not works

Step 5.
compare, step 3, 4
address role + any custom field = works
poi role + any custom field = NOT WORKS

Step 6.
ArcPro fixed, but Arcgis REST api suggest still can't list all address with that number.
Is it because arcgis server version 10.91 ? would version 11.x has same problem?
Let's check other city's locator with version 11.x to find out.
2nd city sample has verison v11
https://transparentgov.net/json2tree/esri/server/folder2.html?url=https%3A%2F%2Fgis.la-quinta.org%2Farcgis%2Frest%2Fservices&org=La+Quinta+CA&_center_lat=33.6634&_center_long=-116.31&_center_zoom=17&select_folder=51&select_layer=-1&arcgis_online_token=&select_folder_text=GoGov_La_Quinta_Geocode_Locator+%3Csup%3EGeocodeServer%3C%2Fsup%3E&select_layer_text=GoGov_La_Quinta_Geocode_Locator+%3Csup%3EGeocodeServer%3C%2Fsup%3E

Step 7.
try 47507
same issue, only number, does not popup anything, at 1 letter will popup.

Step 8.
you can find more address for test from parcel layer
https://transparentgov.net/json2tree/gateway/feature-layer/hover-feature.html?backgroundlayerurl=https%3A%2F%2Fgis.la-quinta.org%2Farcgis%2Frest%2Fservices%2FGoGov%2FGoGov_La_Quinta%2FMapServer%2F2&layer=Parcels&_center_lat=33.6627780828778&_center_long=-116.23855990894387&_center_zoom=18&panto=0

Step 9.
parcel layer is here
https://transparentgov.net/json2tree/esri/server/folder2.html?url=https%3A%2F%2Fgis.la-quinta.org%2Farcgis%2Frest%2Fservices&org=La+Quinta+CA&_center_lat=33.6634&_center_long=-116.31&_center_zoom=17&select_folder=52&select_layer=2&arcgis_online_token=&select_folder_text=GoGov_La_Quinta+%3Csup%3EMapServer%3C%2Fsup%3E&select_layer_text=2+%26%23x21E2%3B+Parcels+%3Csup%3EFeature+Layer%3Csub%3E+esriGeometryPolygon%3C%2Fsub%3E%3C%2Fsup%3E

Step 10.
let's try 3rd city which has verison v11.2
https://transparentgov.net/json2tree/esri/server/folder.html?org=https%3A%2F%2Fgis1.victorvilleca.gov%2Farcgis%2Frest%2Fservices&url=https%3A%2F%2Fgis1.victorvilleca.gov%2Farcgis%2Frest%2Fservices&arcgis_online_token=&select_folder=87&select_layer=-1&select_folder_text=Composite_Locator+%3Csup%3EGeocodeServer%3C%2Fsup%3E&select_layer_text=Composite_Locator+%3Csup%3EGeocodeServer%3C%2Fsup%3E

Step 11.
try 12551, same issue
https://transparentgov.net/json2tree/gateway/feature-layer/geocode-suggest-zoom2location.html?backgroundlayerurl=https%3A%2F%2Fgis1.victorvilleca.gov%2Farcgis%2Frest%2Fservices%2FEnerGov%2FComposite_Locator%2FGeocodeServer&_center_lat=33.928799999999995&_center_long=-118.2468&_center_zoom=13&panto=0

Step 12.
more address for test can be found here
https://transparentgov.net/json2tree/gateway/feature-layer/hover-feature.html?backgroundlayerurl=https%3A%2F%2Fgis1.victorvilleca.gov%2Farcgis%2Frest%2Fservices%2FCOVInternal%2FGISPROD_Address%2FFeatureServer%2F4&layer=Site+Address+Point+Ownership&_center_lat=34.47885982883993&_center_long=-117.36001735857303&_center_zoom=18&panto=0

Step 13.
address point layer is here
https://transparentgov.net/json2tree/esri/server/folder.html?org=https%3A%2F%2Fgis1.victorvilleca.gov%2Farcgis%2Frest%2Fservices&url=https%3A%2F%2Fgis1.victorvilleca.gov%2Farcgis%2Frest%2Fservices&arcgis_online_token=&select_folder=93&select_layer=0&select_folder_text=GISPROD_Address+%3Csup%3EFeatureServer%3C%2Fsup%3E&select_layer_text=0+%26%23x21E2%3B+City+Address+Point+%3Csup%3EFeature+Layer%3Csub%3E+esriGeometryPoint%3C%2Fsub%3E%3C%2Fsup%3E

Step 14.
at this point, we have check 2 other city, who have arcgis server version v11 and v11.2, however, both have same issue with v10.9.
conclusion, version v10.91 is not the cause, rule out.
these people saying old ArcMap locator works fine, but new ArcPro v2.9. does not works.
