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