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