Remember search/replace strings across sessions

Question

Is there a setting in emacs to remember the search/replace string across multiple sessions?

%> emacs -nw fileA
<replace X with Y>

%> emacs -nw fileB
<replace>

should automatically replace X with Y (without having to enter both again)

The desktop.el library (when activated) creates a destop file when killing Emacs, which when opened reveals a (setq search-ring . . . and (setq regexp-search-ring . . ., among other saved settings. However, I've never tried to do what you are proposing -- perhaps its worth looking into. — lawlist, Nov 7, 2014 at 6:23

There's savehist-mode specifically for that kind of saving/restoring:

(savehist-mode 1)
(add-to-list 'savehist-additional-variables 'query-replace-defaults)

savehist-mode must come last for the settings to take

@vfclists: What makes you think so? The way you changed the code, it signals an error because savehist-additional-variables is a void variable at the time the add-to-list is executed.

In the examples I see` (savehist-mode 1)` is placed after the add-to-list command. I think initialization must be done via M-x in a live Emacs session, but in the init.el it has to come after the add-to-list commands
