Abstract
This poster deals with exclusionary queries implemented using the database language SQL and the VA FileMan database system and the retrieval searches involving negated concepts in medical narratives. The poster describes and presents error patterns and designing database queries, underlying comprehension issues regarding negative statements and queries, strategies and software for avoiding false positives in searches, and makes practical recommendations on identifying potential sources of error and avoiding incorrect or misleading results.Mesh：
