We're constantly hit by issues with Windows Search on Server 2012. We have a terminal server of around 14 people, and they use search within Outlook all the time. The index will hit around 1.4 million items, and then maybe a week later, it will rebuild itself and take another two days to do so. It really hits the disk hard and actually causes issues with other VM's on the Hyper V host.
Microsoft have no interest in fixing it, in fact, it's officially not supported in Sever 2016 and will disabled by default, their reason is that it doesn't work properly. Well then fix it MS!
