• The words AND, OR and NOT may confuse the search; try adding quotes: "\"\\"\\\"\\\\"((((\\\\"((practice guidebook) OR (practical guidebook)) to biostatistics AND epidemiology.\\\\\") OR (\\\\"((practice guidebook) OR (practical guidebook)) to statistics AND epidemiology.\\\\\"))) OR (\\\\"((practice guide) OR (practical guide)) to statistical AND epidemiology.\\\\\"))~\\\\"\\\"\\"\"".
• Removing quotes may allow a broader search: \ \\ ((((\\ ((practice guidebook) OR (practical guidebook)) to biostatistics AND epidemiology.\\\ ) OR (\\ ((practice guidebook) OR (practical guidebook)) to statistics AND epidemiology.\\\ ))) OR (\\ ((practice guide) OR (practical guide)) to statistical AND epidemiology.\\\ ))~\\ \.
