The usage of wildcards (use ? for single-character wildcards and use * for multi-character wildcards) and Boolean operators is allowed (And, Or, Not) in all fields with a free text input. A minimum of 3 characters is required when using wildcards. Example : (Franciscan order AND econ*) NOT France In fields that only allow the selection from a pre-defined list (Discipline, Area and Subject Tree) the Boolean/logical operators must be selected at the top of the selection screen: Your choice of relation will be valid for all selected keywords. |
