Few moths ago i raised a Meta request,to delete the indian-movies because its not feeling important that time. Every question that time consist of indian-movies tag and bollywood tag regarding bollywood film questions. But my request got misinterpreted and indian-movies tag made synonym of bollywood tag. Which is inappropriate. Bollywood is part of Indian movies. Indian film industry consist of many regional film industries like Tollywood etc. too.
So in my opinion indian-movies should be a head tag and bollywood as its synonym . Even tollywood should be the synonym of indian-movies too. So by clicking on bollywood tag we will not get tollywoo question which are not related but when we click on indian-movies tag we will get all result of Bollywood,tollywood etc.
They can be kept separate too but making indian-movies synonmym of bollywood is wrong.
It may sound similar to indian-movies and bollywood should not be Tag Synonyms.
