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