• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"sudre, alfred / b. 1820 / histoire _ communism\") OR (\"sucre, alfred / b. 1820 / histoire _ communism\"))".
• Removing quotes may allow a broader search: (( sudre, alfred / b. 1820 / histoire _ communism ) OR ( sucre, alfred / b. 1820 / histoire _ communism )).
• Adding a wildcard symbol may retrieve word variants: (("sudre, alfred / b. 1820 / histoire _ communism") OR ("sucre, alfred / b. 1820 / histoire _ communism"))*.
