Encoding Definitions
The Z39.50 standard makes use of attributes to code a client's query so that the receiving server can process the query correctly. The six encoding definitions provisions for the standard are as follows:
1 - USE or INDEX (Specifies which data field(s) the query should be processed to)
2 - RELATION (Controls the order of numerical expression)
3 - POSITION (Specifies the location of term(s) within the fields for matching query)
4 - STRUCTURE (Specifies the structure of data in the query)
5 - TRUNCATION (Specifies type of truncation processing for query)
6 - COMPLETENESS (Specifies query processing by subfield)
