Few annoyances I noted in the FAQ "What Google search sites does it support?" section. google.co.in is by default in English, you would have to explicitly set it to another language [1]. "Indian" is not a language (Hindi, Malayalam, Bengali etc. is [2]). Farsi is not spelt Farsai [3]
Fixed. Switched example to Turkish and Iranian, as that is were most of your traffic came from this post. Just read an 800 page book on India, can't believe I made that mistake.
