indexed search - pages are indexed many times

[typo27]

Sposibo,
one page is indexed 4 times, and when searching there are 4 identical search results with identical links (links are clear - withouth hash getvar- like index.php?id=1769) - pointing to the same page.

"4) чистить в меню инфо пробовали? и снова инициировать индексацию?"

I would not like to do this - there are few thousand of indexed pages - most of them are in 'not in menu' - so there is no comfort way for visitors to reach them in frontend and to index them again.

The problem is - in search result there are several identical results with identical urls.
