De Abstract. This paper reports information retrieval experiments carried out within the CLEF 2005 ad-hoc multi-lingual track. The experiments focus on the two new languages Bulgarian and Hungarian.

Based on experience from last year, one of our main objectives was to improve and refine the n-gram-based indexing and retrieval algorithms within our system. 1 Introduction In the CLEF 2004 campaign [1], we tested an adaptive fusion system based on the MIMOR model [4, 7] in the multi-lingual ad-hoc track [3].
