Something like

(defun my-move-defun ()
  "Docstring.
@keywords keyword1, keyword2")

(defun my-copy-defun ()
  "Docstring.
@keywords keyword3, keyword4")

(let (keywordlist docstr)
  (mapatoms
   (lambda (symbol)
     (when (and (functionp symbol) (setq docstr (documentation symbol t))
                (string-match "@keywords \\(.*\\)" docstr))
       (add-to-list 'keywordlist
                    (cons symbol (split-string (match-string 1 docstr)
                                               "\\s-*,\\s-*" t))))))
  keywordlist)

=> '((my-copy-defun "keyword3" "keyword4")
     (my-move-defun "keyword1" "keyword2"))
