        a) in case of formatted search the iterator itself is used (like in the first constructor)
        b) in case of formatted search NOT the FormatKey at the fields of the iterator is used, but the respective TextComponent
            is asked (that's why the original iterator is used; by its move the controls behind the TextComponent-interface are
            updated hopefully)
        c) in case of not-formatted search a clone of the iterator is used (because the TextComponent-interfaces don't need to
            be asked)
        (of course needed : the string number i in strUsedFields of a context must correspond with the interface number i in the
        arrFields of the context)
