• If you are trying to use Boolean operators, they must be ALL CAPS: "\"\\"\\\"\\\\"\\\\\"\\\\\\"((\\\\\\\"practical guidebook to ((biostatistical OR biostatistical) OR biostatistical) AND epidemiology.\\\\\\\") OR (((\\\\\\\"practical guide to (statistics OR statistical) AND epidemiology.\\\\\\\") OR (\\\\\\\"practice guide to (statistics OR statistical) AND epidemiology.\\\\\\\"))))~\\\\\\"\\\\\"\\\\"\\\"\\"\"".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"\\"\\\"\\\\"\\\\\"\\\\\\"\\\\\\\"((\\\\\\\\"practical guidebook to ((biostatistical OR biostatistical) OR biostatistical) and epidemiology.\\\\\\\\") OR (((\\\\\\\\"practical guide to (statistics OR statistical) and epidemiology.\\\\\\\\") OR (\\\\\\\\"practice guide to (statistics OR statistical) and epidemiology.\\\\\\\\"))))~\\\\\\\"\\\\\\"\\\\\"\\\\"\\\"\\"\"".
• Removing quotes may allow a broader search: \ \\ \\\ \\\\ \\\\\ ((\\\\\\ practical guidebook to ((biostatistical OR biostatistical) OR biostatistical) and epidemiology.\\\\\\ ) OR (((\\\\\\ practical guide to (statistics OR statistical) and epidemiology.\\\\\\ ) OR (\\\\\\ practice guide to (statistics OR statistical) and epidemiology.\\\\\\ ))))~\\\\\ \\\\ \\\ \\ \.
