Simply do elisp: links with the below function:

[[elisp:(rcd-okular "/home/user/my-file" 2 "small percentage")][small percentage]]

(defun rcd-okular (file &optional page query-string)
  "Open `okular' on PDF FILE.

PAGE is optional page number
QUERY-STRING will be eventually found highlighted."
  (let* ((okular (executable-find "okular"))
	 (args (list file))
	 (args (if page (append (list "-p" (format "%s" page)) args) args))
	 (args (if query-string (append (list "--find" query-string) args) args))
	 (name "*Okular*")
	 (buffer (generate-new-buffer-name name)))
    (cond (okular
	   (apply #'start-process name buffer okular args))
	  (t (user-error "Program `okular' not found")))))
