Current State

As for now, all basic functionalities are already implemented (see features) and it is ready for using on large data. In fact, it searches over 1 million posts on Math StackExchange in pretty much real time with only two low-end servers hosting 3 search instances.

However, this project is still considered a side project, you may not use it for production for many reasons.
