• If you are trying to use Boolean operators, they must be ALL CAPS: "\"\\"\\\"(((((\\\"practical OR \\\"practice) guidebook to biostatistical and epidemiology.\\\\") OR ((\\\"practical OR \\\"practice) guidebook to (biostatistical OR biostatistical) AND epidemiology.\\\\"))) OR ((\\\"practical OR \\\"practice) guide to statistics and epidemiology.\\\\"))~\\\"\\"\"".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"\\"\\\"\\\\"(((((\\\\"practical OR \\\\"practice) guidebook to biostatistical and epidemiology.\\\\\") OR ((\\\\"practical OR \\\\"practice) guidebook to (biostatistical OR biostatistical) and epidemiology.\\\\\"))) OR ((\\\\"practical OR \\\\"practice) guide to statistics and epidemiology.\\\\\"))~\\\\"\\\"\\"\"".
• Removing quotes may allow a broader search: \ \\ (((((\\ practical OR \\ practice) guidebook to biostatistical and epidemiology.\\\ ) OR ((\\ practical OR \\ practice) guidebook to (biostatistical OR biostatistical) and epidemiology.\\\ ))) OR ((\\ practical OR \\ practice) guide to statistics and epidemiology.\\\ ))~\\ \.
