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