Running a search wipes out old search buffer

[spookylukey]

Expected behaviour is that if I run a search for 'foo' (using e.g. projectile-ripgrep) then a search for 'bar', I will now have two search buffers. This is the behaviour of other similar things e.g. projectile-ag command from projectile.el

If you are doing any kind of recursive editing, this is vital behaviour. e.g. I do a search for 'foo' and go down the list of hits, fixing up stuff as I go. While doing a fix, I need to do a search for 'bar', and now my original search (and my position in the buffer) is lost.

Thanks!
