Notes Controlled vocabulary records are stored and indexed in the MARC21 authority data format. Field 009 and 039 are local fields and contain system control numbers. Subfield 9 is a local subfield and contains a form of the heading normalized according to the NACO normalization rules. Please note, the normalized form is lowercase, and subfield-delimiters have been replaced with a space, before multiple spaces are compressed. cql.resultSetId is an index defined by the CQL context set and required by the SRU protocol. When the server performs a search and returns the result, it also returns the name of the resultSet. You can refer to the result set in a subsequent search or display by specifying the returned resultsSetID in a query against the cql.resultSetId index. See The CQL Context Set (version 1.1) for details. cql.serverChoice is an index defined by the CQL context set. It is the default when the index and relation is omitted from a search clause. The server will choose an index for the given term. See The CQL Context Set (version 1.1) for details. Controlled vocabulary descriptions (metadata records) are stored and indexed in the MARC21 bibliographic data format.
