This month's article discusses the query mechanism built into the Z39.50 protocol. There are three types of query defined: type 0, type 1, and type 2. The query is encapsulated in the SearchRequest PDU, discussed last month, and is tagged by its query type value. The type 1 query is an integral part of Z39.50 and is discussed in detail below. Types 0 and 2 are not specific to Z39.50 and are far less important to an understanding of the protocol.
