Did you ever consider a datasource like elasticsearch? If yes what made you choose mongo?

No, and I actually used to work for a company that made a similar type of search engine!

That probably would have worked as well (don't think I considered that specific solution). Mongo came up on top because of it's wide use (among other things), ie it's pretty easy to find support and lots of stories about how to scale it under different scenarios.
