    Specifies whether a field expression satisfies the specified
    condition.

    The product using CDO evaluates a condition clause as true if
    the field expression satisfies the condition specified. The
    field expression specifies the name of a field in the database,
    consisting of a field name and a directory name or context
    variable.

    When you use the keyword NOT, the product using CDO evaluates
    the clause as true if the field expression does not satisfy this
    condition.
