• The words AND, OR and NOT may confuse the search; try adding quotes: "\"\\"\\\"((((\\\"practice guidebook to (biostatistical OR (biostatistics OR biostatistical)) AND epidemiology.\\\\") OR (\\\"practice guidebook to (biostatistical OR (biostatistics OR biostatistical)) AND epidemiology.\\\\"))) OR (\\\"practice guide to (statistics OR statistical) AND epidemiology.\\\\"))*\\\"\\"\"".
• Removing quotes may allow a broader search: \ ((((\ practice guidebook to (biostatistical OR (biostatistics OR biostatistical)) AND epidemiology.\\ ) OR (\ practice guidebook to (biostatistical OR (biostatistics OR biostatistical)) AND epidemiology.\\ ))) OR (\ practice guide to (statistics OR statistical) AND epidemiology.\\ ))*\.
