• If you are trying to use Boolean operators, they must be ALL CAPS: (((("several complex variables and analytics spaces") OR ("several complex variables and analytic spaces"))) OR ("several complex variables and analysis surface")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"several complex variables and analytics spaces\") OR (\"several complex variables and analytic spaces\"))) or (\"several complex variables and analysis surface\"))".
• Removing quotes may allow a broader search: (((( several complex variables and analytics spaces ) OR ( several complex variables and analytic spaces ))) or ( several complex variables and analysis surface )).
• Adding a wildcard symbol may retrieve word variants: (((("several complex variables and analytics spaces") OR ("several complex variables and analytic spaces"))) or ("several complex variables and analysis surface"))*.
