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