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