I've just upgraded to ZCS5 GA FOSS, and have discovered that saved searches no longer seem to work properly.
As an example, we used to have a fairly common search named "Unread Mail". This was an advanced search that just matched all unread items. If I try to recreate that in ZCS5 it works fine as I build the search, but I can't save it unless I also specify some search text in the basic search box at the top of the screen. Obviously this isn't much help - I don't want to search on text, just on the "unread" flag.
Does anyone else see this - unable to save a search unless text is specified?
