<p>Systems and methods for constructing multiple-level filtering information that is applicable for an aggregate of multiple messages. According to various embodiments, a set of filtering values is constructed for a first level as a union of all filter values of the filtering criteria that belong to the intersection set of filter criteria. At the receiver side, the aggregate transport object is filtered based on the first-level filtering information as a first process. The first-level filtering information may be separate of the transport object. If the transport object is not discarded after first-level filtering, then the second-level filtering information, which requires the processing of the transport object, is used to fetch the messages in the bundle.</p> |
