+ <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 processes also SRU
+ GET/POST/SOAP explain requests, returning
+ either the absolute minimum required by the standard, or a full
+ pre-defined ZeeReX explain record.
+ See the
+ <ulink url="&url.zeerex.explain;">ZeeReX Explain</ulink>
+ standard pages and the
+ <ulink url="&url.sru.explain;">SRU Explain</ulink> pages
+ for more information on the correct explain syntax.
+ SRU scan requests are not supported yet.
