There is no option for Oriya as a language in Google.co.in
Moreover, the link google oriya is not like other Indian languages.
There is no option of going to oriya link directly from www.google.co.in
and whatever link is there it looks very bad & the fonts are clumsy
This request was made last year also and no progress is there on this
front from Google India.
I'd request the Google India team to look into this matter and please
update the google.co.in
with Oriya being an option like other Indian
