We describe our official runs for the ad hoc monolingual task in Hungarian for CLEF 2005. We conducted experiments with four stemmers of varying impact. The experiments indicate that stemmers focusing on noun inflection are as effective as more broadly oriented stemmers, and that extensive stemming is especially beneficial for Hungarian monolingual retrieval.
