• 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 biostatistical 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 biostatistical 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 biostatistical and epidemiology.\\\ ))) OR ((\\\ practical OR \\\ practice) guide to statistical AND epidemiology.\\\ ))*\\ \.
