Abstract
Scoring models that make use of proximity information usually improve result quality in text retrieval. Considering that index structures carrying proximity information can grow huge in size if they are not pruned, it is helpful to tune indexes towards space requirements and retrieval quality. This paper elaborates on our approach used for INEX 2009 to tune index structures for different choices of result size k. To allow for comparison as to retrieval quality with non-pruned index structures, we also depict our results from the Adhoc Track.
