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