Gets the derived table targeted per field.

Gets the fields found which target a derived table. Key is field, value is value if the field is present under its alias in the derived table under its name or not at all.

Gets / sets the flag to traverse the inner elements of a FieldCompareSetPredicate. (default is true). Set to false if you use the findings of this crawler to adjust an outer query, as the inner elements of a fieldcompareset are a different scope.
