Hey there.
when we search normally using the search bar in Confluence and then trying to filter the search on a specific Space using the IN SPACE filter on the left side, it always shows No matches found.
I can see all Spaces in the Space Directory.
I already tried a Re-Indexing in Confluence and even a Re-Index from Scratch following this guide: https://confluence.atlassian.com/confkb/how-to-rebuild-the-content-indexes-from-scratch-on-confluence-server-110035351.html
But the issue persists.
Here are two screenshots showing the behavior. I have a Space called Angular. When I try to filter on it in the search it won't find the Space. Happens with all Spaces.


We updated Confluence a month ago, but I don't know if this issue occured before.
Confluence Server Version: 7.12.1
Thank you for any help!
