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