> Mnogosearch indexes URLs. It is exactly like Google: one URL equals to one page. TYPO3 can have many different pages with the same URL due to user groups. This does not fir to mnogosearch at all. Therefore mnogosearch has to be cheated in some way. For example, it can have different URLs for the same page depending on the user group. Then, at the search time, URLs have to be normalized to their typical look. This is possible and not a big problem.

It means that we have to index the same page four times (anonymous, anonymous + #1, anonymous + #2, anonymous + #1 + #2). That is ok. Now how do we tell mnogosearch what kind of result do we need to fetch? We could use tags or categories. This would work but not reliabely. And there is another problem: duplicate search results.
> This final problem is the worse one. Suppose we search for a word that appears in the anonymous content from the example above. If user is in groups #1 and #2, it will give us four results: anonymous page, anonymous + #1, anonymous + #2, anonymous + #1 + #2. These are all different pages to mnogosearch. They have to be filtered out to produce proper results. And this task is not solvable at the moment.
