9.7.1.1 Query usage notes

The QRD and QRF segments are defined in Chapter 2, Section 2.15.

The subject filters contained in the QRD and QRF segments describe the kind of information that is required to satisfy the request. They are defined by local agreement between the inquiring system and the ancillary system. See the Implementation Guide for detailed examples of the use of query filter fields.

The Set ID fields in the various segments (including PID) are used to count the number of segments of one kind transmitted at one level of the hierarchy.

QRD-12-query result level determines the amount of data requested. See Chapter 2, Section 2.18.4.
