== What's "Mizrahi"? == 

 I would be grateful if someone could refer me somewhere where I could learn what "Mizrahi" means, which communities are commonly known as "Mizrahi" and where did this definition come from. From the definition in the introduction to this article, it appears Mizrahi Jews are not defined by a common origin, but rather by a lack thereof, and thus I cannot help feeling this definition had been applied to Mizrahi Jews, rather than self-designated. Why are Georgian Jews considered "Mizrahi" and Cochine Jews not? Is it because there is some fundamental difference between all Mizrahi communities and the Cochine community, or is it simply because nobody ever referred to Cochine Jews as Mizrahi, which Georgian Jews are referred to as such? Could someone informative shed some light please?
