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