I wonder if this might be connected to a wierd problem I keep getting...Basically after doing a few renders, my system resources max out, or DS just shuts down. If there's a cache It might need to be dumped every now and again.
I've noticed the deep search seems to work now, so waiting 5 minutes for it to load something at least nets me more than a waste of time, but I still wish I at least had an option to tell it not to try to help.
