• If you are trying to use Boolean operators, they must be ALL CAPS: "\"\\"\\\"\\\\"\\\\\"\\\\\\"\\\\\\\"\\\\\\\\"((\\\\\\\\\"practical guidebook to (((((biostatistics 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 (((((biostatistics 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 (((((biostatistics 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.\\\\\\\\ ))))~\\\\\\\ \\\\\\ \\\\\ \\\\ \\\ \\ \.
