This report describes Dartmouth College’s approach and r esults for the 2007 TREC Legal Track. Our original plan was to use the Combination of Expert O pinion (CEO) algorithm [1], to combine the search results from several search engines. However, w e did not have enough time to build the index for more than one search engine by the time for subm ission for official runs. The official results described here are based only on the Lemur / Indri [2] search engine.
