• If you are trying to use Boolean operators, they must be ALL CAPS: "\"\\"\\\"\\\\"((\\\\\"practical guidebook to (((biostatistical OR biostatistical) OR (biostatistical OR biostatistical)) OR (biostatistical OR biostatistical)) AND epidemiology.\\\\\") OR (((\\\\\"practical guide to statistical 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 biostatistical) OR (biostatistical OR biostatistical)) OR (biostatistical OR biostatistical)) and epidemiology.\\\\\\") OR (((\\\\\\"practical guide to statistical and epidemiology.\\\\\\") OR (\\\\\\"practice guide to statistical and epidemiology.\\\\\\"))))~\\\\\"\\\\"\\\"\\"\"".
• Removing quotes may allow a broader search: \ \\ \\\ ((\\\\ practical guidebook to (((biostatistical OR biostatistical) OR (biostatistical OR biostatistical)) OR (biostatistical OR biostatistical)) and epidemiology.\\\\ ) OR (((\\\\ practical guide to statistical and epidemiology.\\\\ ) OR (\\\\ practice guide to statistical and epidemiology.\\\\ ))))~\\\ \\ \.
