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