+ It has four possible settings.
+ 'get', enables SRU access through GET requests. 'post' enables SRU/POST

+ <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

+ <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>

+ <listitem>
+ <para>
+ Specifies a filter which allows Pazpar2 to only include

+ Unmatched records will be ignored.
+ The filter takes the form name, name~value, or name=value, which
+ will include only records with metadata element (name) that has the

+ If value is omitted all records with the named metadata element

+ targets to return records before releasing the block.
+ If no target is preferred, the block=pref will identical to block=1,

+ <listitem>
+ <para>
+ Specifies attributes for limiting a search to a field - using

+ a field to a value is identical to an existing cclmap field; in
+ other cases the field must be specified in a different way - for
+ example to match a complete field (rather than parts of a subfield).
+ </para>
+ <para>
+ The value of limitmap may have one of three forms: referral to
+ an existing CCL field, a raw PQF string or a local limit. Leading string
+ determines type; either <literal>ccl:</literal> for CCL field,
+ <literal>rpn:</literal> for PQF/RPN, or <literal>local:</literal>
+ for filtering in Pazpar2.
