incategory does not work?

Hi,

got a mediawiki installation (1.16). I have some categories with articles in it. Now I try to search with the parameter incategory like:

+incategory:"Glossar"

But it does not work. Even in a new (tested) installation it does not work. Can anyone help me please as this should work.

Thanks!

It is a lucene-search-specific featutre not present in default search engine.

ah thanks a lot. Wondering why this is not mentioned on the help:searching site.
