• If you are trying to use Boolean operators, they must be ALL CAPS: "\"\\"\\\"\\\\"\\\\\"\\\\\\"\\\\\\\"\\\\\\\\"\\\\\\\\\"\\\\\\\\\\"((\\\\\\\\\\\"practical guidebook to (((biostatistics OR 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 (((biostatistics OR 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 (((biostatistics OR 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.\\\\\\\\\\ ))))~\\\\\\\\\ \\\\\\\\ \\\\\\\ \\\\\\ \\\\\ \\\\ \\\ \\ \.
