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