15 <refpurpose>transforming SRU web service requests to Z3950 metaproxy packages</refpurpose>
18 <refsect1><title>DESCRIPTION</title>
20 The <literal>sru_z3950</literal> metaproxy filter transforms valid
21 SRU/GET or SRU/SOAP requests to Z3950 requests, and wraps the
22 received hit counts and XML records into suitable SRU response messages.
25 It supports only the SRU <literal>searchRetrieve</literal> operation, which
26 is transformed into successive Z3950 <literal>init</literal>,
27 <literal>search</literal> and <literal>present</literal> requests.
30 The SRU <literal>scan</literal> operation is not supported.
33 The SRU <literal>explain</literal> operation is not supported.
34 A configuration for a full SRU server needs to prepend the
35 <literal>zeerex_explain</literal> filter in front of this
36 <literal>sru_z3950</literal> to serve explain requests. This filter
37 still needs to be implemented.
40 This filter does not handle CQL-to-PQF translations. In case that
41 the backends do not understand CQL, you need to prepend the
42 <literal>cql_pqf</literal> metaproxy filter. This filter
43 still needs to be implemented.
47 <refsect1><title>EXAMPLES</title>
49 A typical configuration looks like this:
51 <filter type="sru_z3950"/>
