• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease ligand decreases cocaine process ) OR ( decrease NOT decrease OR decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease ligand decreases cocaine process ) OR ( decrease not decrease or decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease ligand decreases cocaine process ) OR ( decrease not decrease or decrease ))*.
