We are running our Xenforo forum on a Windows machine with IIS8 and PHP7. All is working well. We would like to buy the Enhanced Search Support, but we need Elasticsearch for it. I'm able to install it and run it as a windows service, but is that enough. For the installation I see curl commands which are not part of Windows. I can install an emulator box, but is it needed? How does Xenforo communicate with the elasticsearch service? I also saw somewhere that Java is needed to make elasticsearch work?
