Try this script in a button:

on mouseUp
  push card                            -- save the current card
  ask "Grep for what"                  -- what do you want to grep for?
  put empty into cardList              -- start with no cards in list

  find it                              -- find 1st occurence of text
  put the id of this card into startCard -- save it to test for end of list
  repeat
    put the id of this card & return after cardList  -- add this card to list
    find it                                          -- find the next card
    if the id of this card is startCard then exit repeat -- are we done?
  end repeat

  pop card                                      -- back to original card
  put cardList into card field "grep list"      -- display the list
end mouseUp

This does have one known limitation; if the first card on which the string
is found has more than one occurence of the string, only that card will be
shown.  This may be a major drawback for some applications and no problem
for others.  There may be a simple way around that but I haven't looked too
deeply for one yet.  The code that needs to be changed is the line
   if the id of this card is startCard then exit repeat -- are we done?

This has been discussed in previous articles in this newsgroup. You should
be able to obtain a copy from people who have been reading the newsgroup.
