I have played a little with the search engine. It seems that when I search words using some of the special danish letters (æøå and ÆØÅ), it just do not work.
First I enter "rådgivning" and hit the sarch button - it then changes the word to "rådgivning" in the search field and telling me that nothing was found. Then I hit the search button again, and now it finds a lot of pages that has nothing to do with the word I was searching for..

This is a little "trals" as we say in danish.
