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