Query Z39.50 Query Servers

After you enable federated search of a Z39.50 query server through the standard ACI (Autonomy Content Infrastructure), you can send Query actions in PQF or CQL format to the DAH. The DAH then passes the queries to the query servers it connects to.

You can use the following Query action parameters:

  • Text
  • MaxResults
  • DatabaseMatch
  • TotalResults
  • Start

For details on these settings, refer to the IDOL Server Reference.

Example Queries

PQF:

http://host:port/action=Query&Text=cat
http://host:port/action=Query&Text="Abyssinian Bobtail"
http://host:port/action=Query&Text=@and fat cat
http://host:port/action=Query&Text=@attr 1=4 @attr4=1 "hot tin roof"

CQL:

http://host:port/action=Query&Text=cat
http://host:port/action=Query&Text="Abyssinian Bobtail"
http://host:port/action=Query&Text=fat and cat
http://host:port/action=Query&Text=title="hot tin roof"

where:

  • host is the IP address (or host name) of the machine on which the DAH is installed.

  • port is the port number that clients use to communicate with the DAH (you specify this option in the Port setting in the [Server] section of the DAH configuration file).

NOTE: PQF (Prefix Query Format) and CQL (Common Query Language) are non-IDOL syntax standards. For more information, refer to the external documentation.
