FSLogix - Search issues

Hello,

Does anyone know what happens when an FSL server reboots when there are current connections using the containers? I'm beginning to suspect that this is what's causing search issues.

I've been testing logging off vmware sessions while the server is online and it picks up the index as 'complete'. I'm noticing after the reboot, for anyone that had a session running, it resets the index back to 0 and has to rebuild it from scratch. 

I currently have a single windows server (ntfs) for ODFC (no profile) containers.
