[Typo3] Indexed Search and weird behavior

[Olivier Simah]

Hi everyone,
Here is a weird behavior of the "Indexed Search" that I can not explain:
    - when I create a page and I see it for the first time, no problem, it 
is indexed
    - when I change this page and reload it in the browser, Typo3 do not 
detect the change

So it is not indexed again and the results of the search become completly 
false (if for example, some content has be removed, the text still appear in 
the search results)

Can anyone give me any clue?

Thanks
