Oh! Unfortunatelly now I see that deletion is not ideal... :-(
But !!!
I found that It's working with "delay" ;-)
I was confused but I'll explain.
Using next steps: 1 - what my program does, 2 - what is the result in what case.

1 - what my program does
in general my program try to do the next:

1. reindex Lucene index if something changed
   (file modified, dleted, new appeared), all unmodified remains untouched
2. do search
3. show result

2 - what is the result in what case
I force my program to delete one file from index, and then to search
for words that was only in deleted file.
Still unsutisfied - the unexpected result that the words found ...

So, I start my program again and now it does nothing with index !
And search fails ! :-))))

I can't figure out whay that. Whay deletion comes true not instantly.

I've really _CLOSED_ and even assigned null(s) to all index readers and
writers !!

So, I can't answer you completely, but for now I satisfied by this
partial result.

MB> If you solved it, do you have any hint for me ?

the problem to
