Actually, it's the contrary : as a regular state, only few cards (the 4  
first ones in the stack) must remain non searchable ; while all the  
others must remain searchable.

So, the user write a small set of keywords ; I search all the cards  
(except 4) to find those where this set is present ; I display the list  
of this cards to the user ;  when the user click on one line of this  
list, I go to the corresponding card ; there I use the JacqÉric' script  
(or the Jim' one :-)) in order to find all occurrences of each keywords  
and highlight them on this current card.

In order to never search in the four first cards, I used the Éric' idea  
( using cardNames that allow to use the repeat for each form) :

put the cardNames of this stack into CardList
delete line 1 to 4 of CardList
repeat for each line tCd in CardList
set the dontSearch of tCd to true
end repeat
set the dontSearch of this cd to false --the only one that remains  
searchable
-- then I search keywords in this current cd, highlight them  
--and again on CardList, I set the dontSearch to false

Of course the race I quickly programmed is just for fun (I mean, the  
fact that my app. is currently (and temporarily)  choosing at random  
between Jim' and JacqÉric' solution).
In any case, my problem is solved ; the two scripts are very fast : for  
the user, the display of a card with the keywords highlighted is  
practically instantaneous ! (I set the cursor to watch, but, it is  
nearly to perceive it !!!), even though the two handlers are included  
in a quite larger one.
And I think that I am far from the moment when the number of cards in  
my app. will entail a noticeable delay !

Again a lot of thanks to you (and to Éric and Jim)

Best regards from Grenoble
