Ok, that's the limit of the Joomla/seblod integration here.
on the first hand it is said that the Joomla smart search is not reliable, so don't use it, use seblod search instead. And it's true com_finder doesn't know the seblod menu items so it won't be able to generate right sef urls
on the second hand the seblod search is not as advanced if should be. At least I whish there is someone here giving us some hints where to start from for the relevance addition.
The right solution would be to use a third party search engine and make it work with the cck content types in webservices but it is way harder to do
thanks
