In order to restrict search queries to require specific fields to be populated as mandatory input for each query the corresponding field definition has to be changed.
By default the query field section does not restrict query execution based on mandatory field value input.
The ‘Input required for search’ checkbox is not checked in the in the ‘Edit Field Definition’ window of the Index field definitions.
You can enable the ‘Input required for search’ checkbox for each field that you want to set as a mandatory part of the search query. A field value will be required for each query that is performed. The ‘Input required for search’ checkbox is part of ‘Edit Field Definition’ window of the Index field definitions and can be selected for each applicable field.
