Try adding the full address to the node, that should help, at least “O” and “Jaipuria Sunrise Greens” should both appear in the address fields. Otherwise a geocoder has no way of knowing that “Jaipuria Sunrise Greens” is also part of the address.
In my answer to your previous question I suggested addr:place=Jaipuria Sunrise Greens. You used addr:place=O instead. You can probably use either approach, but the tagging scheme is slightly different.
Tagging scheme 1 addr:flats=001 (or addr:unit?) addr:housenumber=O (or addr:housename=O or maybe name or addr:block=? though I am not sure how well these work) addr:place=Jaipuria Sunrise Greens addr:city=Zirakpur Example
Tagging scheme 2 addr:housenumber=001 addr:place=O addr:suburb=Jaipuria Sunrise Greens addr:city=Zirakpur Example
I think either should work, but let us know if it doesn’t!
