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