Quick Search is not displayed when folding is activated

I have a partition dc=example,dc=com
In there I have ou=import
And even deeper there is ou=users and ou=groups
If I want to search a group via quicksearch and click on ou=groups and fill in cn=foo it finds nothing
If I do the quicksearch from ou=import with subtree enabled, it finds objects
But I only want to search underneath ou=groups
