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