• If you are trying to use Boolean operators, they must be ALL CAPS: "\"\\"\\\"(((\"practical OR \"practice) guidebook to ((biostatistical OR statistical) OR (biostatistics OR (biostatistical OR statistical))) 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 OR statistical) OR (biostatistics OR (biostatistical OR statistical))) and epidemiology.\\\\\") OR ((\\"practical OR \\"practice) guide to statistics and epidemiology.\\\\\"))\\\\"\\\"\\"\"".
• Removing quotes may allow a broader search: \ \\ ((( practical OR practice) guidebook to ((biostatistical OR statistical) OR (biostatistics OR (biostatistical OR statistical))) and epidemiology.\\\ ) OR (( practical OR practice) guide to statistics and epidemiology.\\\ ))\\ \.
