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