• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"odor coding using variable parameters\") OR (\"_ pitons python python programming\"))~".
• Removing quotes may allow a broader search: (( odor coding using variable parameters ) OR ( _ pitons python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("odor coding using variable parameters") OR ("_ pitons python python programming"))*.
