Description
int
yaz_ccl_parse ( int id, string query, array & result)
This function invokes the CCL parser. It converts a given
CCL FIND query to an RPN query which may be passed to the
yaz_search() function to perform a search.
To define a set of valid CCL fields call
yaz_ccl_conf() prior to this function.
If the supplied query was successfully
converted to RPN, this function returns TRUE, and the index
rpn of the supplied array
result holds a valid RPN query.
If the query could not be converted (because of invalid syntax,
unknown field, etc.) this function returns FALSE and three
indexes are set in the resulting array to indicate the cause
of failure: errorcodeCCL error code (integer),
errorstringCCL error string, and
errorposapproximate position in query of failure
(integer is character position).
