Represents a compound filter expression for container records consisting of a collection of IFieldFilterExpressions.
A Compound filter expression takes the form:
<IFilterExpression><LogicalFilterExpressionOperator><IFilterExpression>
[<LogicalFilterExpressionOperator><IFilterExpression>...]
For example:
(bid > 5) AND (ask < 6)
or
(bid > 5) AND (ask < 6) AND (coupon >= 3)
Note: Every occurrence of LogicalFilterExpressionOperator in the filter is of the same type; that is AND or OR only.
