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