[Option] namedResultSets [Level] Connection [Default] 1 [Description] 
If false (0), then the ZOOM client should not attempt to create multiple result sets. Instead, the result-set name default is used for all result sets generated on the server, so that the second result set invalidates the first and so on. This option is required because there are Z39.50 servers in production that do not support named result sets correctly and produce unreliable results if they are used. In addition, ZOOM is sometimes used in high-load environments where it is simply not practical to keep result sets around when they are not needed.
