Constructs a `DefaultOperator` object for use in general search operations within the RCSB PDB.
This operator is used when a simple, non-specific search operation is needed, based on a single value.
The `DefaultOperator` can be employed in scenarios where the search criteria do not require complex conditions
or additional logic.
Usage

Value
An object of class `DefaultOperator` representing the default search operator.
This object can be used directly in query formulations or further manipulated within complex search logic.
Arguments
