• If you are trying to use Boolean operators, they must be ALL CAPS: "\"\\"\\\"\\\\"(((\\\"practical OR \\\"practice) guidebook to ((biostatistical OR biostatistics) OR statistics) 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) OR statistics) 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) OR statistics) and epidemiology.\\\\ ) OR ((\\ practical OR \\ practice) guide to statistical and epidemiology.\\\\ ))~\\\ \\ \.
