Seafile Pro Server Search not working after upgrade to 7.0.7 and 7.0.8

Hello,

After upgrading from 6.13 to 7.0.7 and then 7.0.8 the search function has stopped working. I am running the latest jdk 1.8 and when I try to run ./pro/pro.py search -update it fails

Updating search index, this may take a while…

Any thoughts on how to resolve this?
Thanks

Maybe the same as : Seafile pro edition 7.0.8 is ready!
