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