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