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