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