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