I only believe that MNO had some limitation with TYPO3 integration  
when yiou have logged in FE users
and you don't want to show search results of a group a logged in user  
doesn't have access to.
Dmitry, is this still true?

A friend of mine forked the TYPO3 mno extension to make that work  
properly, but it's not
in a state that it can be released.

The alternative forms can be easily added to any search engine...
You only need some libraries... But they are open source. TO bad
that indexes seach is not to smart....

I do believe it is available for windows, but you need to pay....

I personally used it to index office documents and indexing documents
with a total size of over 20-30GB is not a problem at all for MNO.
