• 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 statistical AND epidemiology. ))) OR ( (practical OR practice) guidebook to biostatistics AND epidemiology. ))) OR ((((( (practical OR practice) guidebook to biostatistical AND epidemiology. ) OR ( (practical OR practice) guidebook to statistical AND epidemiology. ))) OR ( (practical OR practice) guidebook to biostatistics AND epidemiology. ))))) OR ((((( (practical OR practice) guidebook to biostatistical AND epidemiology. ) OR ( (practical OR practice) guidebook to statistical AND epidemiology. ))) OR ( (practical OR practice) guidebook to biostatistics AND epidemiology. ))))) OR ((((( (practical OR practice) guidebook to biostatistical AND epidemiology. ) OR ( (practical OR practice) guidebook to statistical AND epidemiology. ))) OR ( (practical OR practice) guidebook to biostatistics AND epidemiology. ))))) OR ( (practical OR practice) guide to statistics 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 statistical and epidemiology. ))) OR ( (practical OR practice) guidebook to biostatistics and epidemiology. ))) OR ((((( (practical OR practice) guidebook to biostatistical and epidemiology. ) OR ( (practical OR practice) guidebook to statistical and epidemiology. ))) OR ( (practical OR practice) guidebook to biostatistics and epidemiology. ))))) OR ((((( (practical OR practice) guidebook to biostatistical and epidemiology. ) OR ( (practical OR practice) guidebook to statistical and epidemiology. ))) OR ( (practical OR practice) guidebook to biostatistics and epidemiology. ))))) OR ((((( (practical OR practice) guidebook to biostatistical and epidemiology. ) OR ( (practical OR practice) guidebook to statistical and epidemiology. ))) OR ( (practical OR practice) guidebook to biostatistics and epidemiology. ))))) OR ( (practical OR practice) guide to statistics and epidemiology. ))~".
