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