Lucene exact property match

[billerby]

I have two nodes of the type acroduktion in my repository with the follwing property values:

node one: ac:titel="Junekvintetten"
node two: ac:titel="Junekvintetten & Fribo"

Issuing the following lucene query:
+TYPE:"{http://www.acando.com/model/1.0}produktion" AND +@ac\:titel:"Junekvintetten"

returns both the nodes. I only want the first one. How can I achieve this? I guess the space character is the reason for the match. Is there some "exact match" keyword I can use?

Thanks

Ok, I did not search the forums enough:
