Previously, you said that you want to `group' files.  So if you save
fileA and fileB `together', then they should share the same search
string.  That's at least what I understood from your previous message.

So we're back to square one.  You want to make isearch-string
buffer-local.  Then you want to make sure that the buffer-local value
is saved when you exit Emacs and loaded again when you enter Emacs
again.

First, please try whether it works to make the variable buffer-local.

Secondly, investigate how session.el or desktop.el allows you to save
per-buffer settings.

If that all pans out well, the following should do it:

(1) Tell Emacs that isearch-string is buffer-local, by putting
    (require 'isearch)
    (make-variable-buffer-local 'isearch-string)
    into ~/.emacs.

(2) Tell session.el or desktop.el to save the value of isearch-string
    for each buffer.
