I'm pretty much out of ideas unfortunately.  Everybody else with this  
same issue (at least with the symptoms you described) have indicated  
that the fixes from last month fixed everything.

In short, what is happening is that the search results are being  
offloaded from session storage to cache storage once they reach a  
certain size.  Otherwise, your session size grows extremely large -  
and since the session needs to be loaded every time a page/endpoint is  
accessed, it is imperative that we minimize the session size as much  
as possible.

The only thing I can think of is that your cache storage backend is  
not writable by the webserver.  You should make sure that cache files  
are actually appearing in the directory you have configured to store  
cache files in.
