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