Step 1.
attach address number along with business name, in POI layer,
Step 2.
everything else keep the same, works fine.
Step 3.
Step 4.
Step 5.
it works on my model, but not works well on motorola flex, because flex has limit max 10 results on drop down. Also flex show POI at bottom, a lot of unreal street address take up the space of 10 limit. At the result, user would not see any POI.
Step 6.
compare to previous screen, search 3090 does not show POI on flex
Step 7.
further improvement made on source data, add comma after the address number, let it work as POI indicator, when user type extra commna, indicate user interested in bring up POI business name instead of a bunch of un-real-street-address.
Step 8.
re-do everything and test again, with model # 2640 which is specially made for motorola-flex test.
Step 9.
3090, does not popup POI business, same as before, the real change is you type extra comma, 
Step 10.
when you type extra comma, it indicate you interested in bring up POI business name, instead of previous unreal address.
Step 11.
however, it ignore the comma, period, or space, or any other special char after the number.
you search 3090, 3090. 3090# 3090+space, it ignore all of them
Step 12.
there are 3 exception, 1). single quote (') works
Step 13.
2). email at sign @ also works
Step 14.
3). grave accent (`) works too.
Step 15.
summary, following 3 char after number can be used as POI indicator, the other special char will be ignored
1). single quote (')
2). email at (@)
3). grave accent (`)
while the source data, you do not have to add these extra char, following format just works.
Step 16.
2640 flex model works
Step 17.
Step 18.
Step 19.
