+ (mp::filter::SRUtoZ3950)</title>
+ <para>
+ This filter transforms valid
+ SRU GET/POST/SOAP searchRetrieve requests to Z3950 init, search,
+ and present requests, and wraps the
+ received hit counts and XML records into suitable SRU response
+ messages.
+ The <literal>sru_z3950</literal> filter does only process SRU
+ GET/POST/SOAP explain requests in a very crude fashion, returning
+ the absolute minimum required by the standard. Full ZeeReX
+ explain support is added by including the
+ <literal>zeerex_explain</literal> filter before the
+ <literal>sru_z3950</literal> filter.
