+ support.
+ It has four possible settings.
+ 'get', enables SRU access through GET requests. 'post' enables SRU/POST
+ support, less commonly supported, but useful if very large requests are
+ to be submitted. 'srw' enables the SRW (SRU over SOAP) variation of
+ the protocol.
+ </para>
+ <para>
+ A value of 'solr' anables SOLR client support. This is supported
+ for Pazpar version 1.5.0 and later.

+ <term>pz:pqf_prefix</term>
+ <listitem>
+ <para>
+ Allows you to specify an arbitrary PQF query language substring.
+ The provided string is prefixed the user's query after it has been
+ normalized to PQF internally in pazpar2.
+ This allows you to attach complex 'filters' to queries for a given
+ target, sometimes necessary to select sub-catalogs
+ in union catalog systems, etc.

+ <term>pz:pqf_strftime</term>
+ <listitem>
+ <para>
+ Allows you to extend a query with dates and operators.
+ The provided string allows certain substitutions and serves as a
+ format string.
+ The special two character sequence '%%' gets converted to the
+ original query. Other characters leading with the percent sign are
+ conversions supported by strftime.
+ All other characters are copied verbatim. For example, the string
+ <literal>@and @attr 1=30 @attr 2=3 %Y %%</literal>
+ would search for current year combined with the original PQF (%%).
