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