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