• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"monotypic taxol\") OR (((\"monotypic saxon\") OR (\"monotypic saron\"))))) OR (\"monotypic axon\"))".
• Removing quotes may allow a broader search: (((( monotypic taxol ) OR ((( monotypic saxon ) OR ( monotypic saron ))))) OR ( monotypic axon )).
• Adding a wildcard symbol may retrieve word variants: (((("monotypic taxol") OR ((("monotypic saxon") OR ("monotypic saron"))))) OR ("monotypic axon"))*.
