• The words AND, OR and NOT may confuse the search; try adding quotes: "(( science, decouverte, inventiony, electrodynamic, physique ) or ( science, decouverte, (inventor, OR investor,) electrodynamics, physique ))".
• Adding a wildcard symbol may retrieve word variants: (( science, decouverte, inventiony, electrodynamic, physique ) or ( science, decouverte, (inventor, OR investor,) electrodynamics, physique ))*.
