( resource id, array config)
This function configures the CCL query parser for a target
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.
Example 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
$fields["ti"] = "1=4";
$fields["au"] = "1=1";
$fields["isbn"] = "1=7";
