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