I am using twitter api to get some tweets. However I realized that for #congress I also get tweets about the congress in US. How do I restrict it to Indian congress only? I can limit it based on the location, but then I lose out on tweets about Indian congress by people living in the US. Also if I search for Indian National Congress or INC it reduces the no of tweets as most of the people just say congress.
One suggestion might be to use different search criteria, like names of specific Indian politicians. Another might be to look at tweets in Hindi. I imagine there is a rich corpus of tweets in Hindi that will give you what you want. Also, there may be another hashtag to use as a filter.
Hope this helps.
