How can I easily repeat emacs find-grep

I would like to be able to easily repeat a find-grep. Ideally, it would work on recompile, which is what the g char runs. But at least when I run find-grep, it should start with the string that I last used in the same session, as a default. I have searched, but not found... Kind of ironic to be searching for an answer about searching...

Doesn't g do what you request already? For me it does.

But I'm talking about find-grep-dired, which might be useful for what you want to do.

I use find-dired+.el, in addition to vanilla find-dired.el. But I think that the latter probably does the right thing too.

Here's the doc string of find-grep-dired from find-dired+.el:

find-grep-dired is an interactive Lisp function in `find-dired+.el'.

(find-grep-dired DIR REGEXP &optional DEPTH-LIMITS EXCLUDED-PATHS)

Find files in DIR containing a regexp REGEXP.
The output is in a Dired buffer.
The `find' command run (after changing into DIR) is essentially this,
where LS-SWITCHES is `(car find-ls-option)':

  find . -exec grep find-grep-options REGEXP {} \; LS-SWITCHES

Thus REGEXP can also contain additional grep options.

Optional arg DEPTH-LIMITS is a list (MIN-DEPTH MAX-DEPTH) of the
 minimum and maximum depths.  If nil, search directory tree under DIR.

Optional arg EXCLUDED-PATHS is a list of strings that match paths to
 exclude from the search.  If nil, search all directories.

When both optional args are non-nil, the `find' command run is this:

  find . -mindepth MIN-DEPTH -maxdepth MAX-DEPTH
         \( -path *edir1* -o -path *edir2* ... \)
         -prune -o -exec grep find-grep-options REGEXP {} \;
         LS-SWITCHES
