• If you are trying to use Boolean operators, they must be ALL CAPS: ((((((\ practical guidebook to statistical AND epidemiology.\ ) OR (\ practical guidebook to statistical AND epidemiology.\ ))) OR (((\ practice guidebook to ((biostatistics OR statistical) 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 statistical and epidemiology.\ ))) OR (((\ practice guidebook to ((biostatistics OR statistical) OR statistical) and epidemiology.\ ) OR (\ practice guidebook to statistical and epidemiology.\ ))))) OR (\ practical guide to statistics and epidemiology.\ ))~".
• Adding a wildcard symbol may retrieve word variants: ((((((\ practical guidebook to statistical and epidemiology.\ ) OR (\ practical guidebook to statistical and epidemiology.\ ))) OR (((\ practice guidebook to ((biostatistics OR statistical) OR statistical) and epidemiology.\ ) OR (\ practice guidebook to statistical and epidemiology.\ ))))) OR (\ practical guide to statistics and epidemiology.\ ))*.
