vim: remember search & ex cmd history across vim reload

hi:

I kind of forgot somewhere (maybe user-manual) I saw a way to make vim
remember all search & ex cmd history, across vim instances, even
remember all history info after a vim reload.
but I couldn't find out how. is it viminfo manipulation or something else?
I need this since I find it might be useful to just get back a lengthy
search/external cmd back for a new doc...

thanks in advance!

regards
ping
