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