At the moment a project is running to translate all content in English, to make the database more international. This will take a lot of time, because more than 40.000 descriptions have to be migrated. So for the coming months there will be a mixture of Dutch and English descriptions. The purpose is to make everything English and remove the Dutch, French and German searchpages.
The list of countries and states has disappeared from the searchscreen. Main reason that those were frequently used by search robots. Another reason is that maintaining is a lot of work, and because you can enter everything in the search windows, the links are not necessary.
For an advanced search on more fields or a combination of fields, you can click on 'Organs' in the menu on the left.
