User type city, then soi, and lastly user select housenumber. e.g. Bang Rak, Si Lom 17 Soi, 2/A
Do we need to correlate housnumbers to the main road? In this case to Si Lom Rd. Is it possible, that users do not know the exact soi, only they know housenumber and it belongs to one of the SOIs of Si Lom Road. Therefore they would like to search to Si Lom Road, then type housenumber, and get the location of 2/A in Si Lom 17 Soi, or get the full list of 2/A and then user can select which one is better for them.
This would highly improve the usability of address points.
