That's what ag.el (which drives the `ag' search command) does. For
instance:

*ag search text:foo dir:/home/oscar/bar*

which makes convenient locating an ag buffer by searched text and/or
directory. It tends to create large buffer names which don't play well
with tools that have a limited sprace for buffer names (ibuffer) but
otherwise it is useful.

I do that with compilation-buffer-name-function.
