• 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) OR (practical guide)) to statistics 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) OR (practical guide)) to statistics 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) OR (practical guide)) to statistics and epidemiology.\\ ))*\.
