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