A series of information retrieval experiments was earned out with a computer installed in a medical practice setting for relatively inexperienced physician end-users. Using a commercial MEDLINE product based on the vector space model, these physicians searched just as effectively as more experienced searchers using Boolean searching. The results of this experiment were subsequently used to create anew large medical test collection, which was used in experiments with the SMART ~trieval system to obtain baseline performance data as well as compare SMART with the other searchers.
