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