• If you are trying to use Boolean operators, they must be ALL CAPS: (((("atom-bond connectivity bank index") OR ("atom-bond connectivity a index"))) OR ("atom-cloud connectivity bank index")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"atom-bond connectivity bank index\") OR (\"atom-bond connectivity a index\"))) or (\"atom-cloud connectivity bank index\"))".
• Removing quotes may allow a broader search: (((( atom-bond connectivity bank index ) OR ( atom-bond connectivity a index ))) or ( atom-cloud connectivity bank index )).
• Adding a wildcard symbol may retrieve word variants: (((("atom-bond connectivity bank index") OR ("atom-bond connectivity a index"))) or ("atom-cloud connectivity bank index"))*.
