• If you are trying to use Boolean operators, they must be ALL CAPS: "\"\\"\\\"\\\\"\\\\\"(((\\\\"practical OR \\\\"practice) guidebook to ((biostatistics OR biostatistical) OR biostatistical) AND epidemiology.\\\\\\") OR ((\\\\"practical OR \\\\"practice) guide to 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) and epidemiology.\\\\\\\") OR ((\\\\\"practical OR \\\\\"practice) guide to statistical AND epidemiology.\\\\\\\"))~\\\\\\"\\\\\"\\\\"\\\"\\"\"".
• Removing quotes may allow a broader search: \ \\ \\\ \\\\ (((\\\ practical OR \\\ practice) guidebook to ((biostatistics OR biostatistical) OR biostatistical) and epidemiology.\\\\\ ) OR ((\\\ practical OR \\\ practice) guide to statistical AND epidemiology.\\\\\ ))~\\\\ \\\ \\ \.
