• If you are trying to use Boolean operators, they must be ALL CAPS: "\"\\"\\\"\\\\"(((((\\\\"practical OR \\\\"practice) guidebook to (statistical OR biostatistics) AND epidemiology.\\\\\") OR ((\\\\"practical OR \\\\"practice) guidebook to (statistical 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 (statistical OR biostatistics) and epidemiology.\\\\\\") OR ((\\\\\"practical OR \\\\\"practice) guidebook to (statistical 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 (statistical OR biostatistics) and epidemiology.\\\\ ) OR ((\\\ practical OR \\\ practice) guidebook to (statistical OR biostatistics) AND epidemiology.\\\\ ))) OR ((\\\ practical OR \\\ practice) guide to statistics and epidemiology.\\\\ ))~\\\ \\ \.
