This function configures the CCL query parser for a server with definitions of access points (CCL qualifiers) and their mapping to RPN. To map a specific CCL query to RPN afterwards call the yaz_ccl_parse() function. Each index of the array config is the name of a CCL field and the corresponding value holds a string that specifies a mapping to RPN. The mapping is a sequence of attribute-type, attribute-value pairs. Attribute-type and attribute-value is separated by an equal sign (=). Each pair is separated by white space.
Esempio 1. CCL configuration
In the example below, the CCL parser is configured to support three CCL fields: ti, au and isbn. Each field is mapped to their BIB-1 equivalent. It is assumed that variable $id is the connection ID.
