The fact that you use quora, a network very popular in India, and expect indian content to not be there is like going to a Italian restaurant and asking why is the menu full of pastas.
I don't use Quora. Quora just pops up in my search results all the time.
There is nothing innately Indian about Quora. Indians are just overrepresented on it.
Just add '-site:quora.com' to your search query to avoid Quora altogether
