I use GW 2014 R2 Build 123047 and have a problem using the quicksearch in shared folders.
Everything works fine until i share the folder, as soon as I share the folder, the quicksearch doesn´t show any results.
I tried this on very smal folders and normal ones, so I think it is not a time-issue.
When i "unshare" this folder, the quicksearch gives me results.

Is it a feature??
Any suggestions?

Thank you!
