Address with Unit Numbers

Hi,
Many thanks for this awesome plugin.
It works great but the only problem I see is its only searching from street addresses but not including unit numbers?
I am using this for Australia where if I enter a Unit number in the start, it doesnt show any results. When I remove the unit number, it display the results with only street name.
Can you advise how can we include street numbers as well?
Example address: 2 / 9 cross street Hove, SA 5048, Australia.
If you will remove 2 in the start that is the unit number, only then it will display results.
Many thanks for help.
