- Filtering.
+ Limits the search to a given set of targets specified by the
+ filter. The filter consists a comma separated list of
+ setting+operator+args pairs. The setting is a Pazpar2 setting
+ (such as pz:id).
+ The operator is either = (string match)
+ or ~ (substring match). The args is a list of values separated
+ by | (or , one of the values). The idea is that only targets
+ with a setting matching one of the values given will be included
+ in the search.

+
+ limit
+
+
+ Narrows the search by one or more fields (typicall facets).
+ The limit is sequence of one or more field=value pairs separate
+ by comma.
+ A value that contains a comma should be escaped by backslash (\).
+ The pz:fazetmap configuration item defines how the searches are

+ Specifies the maximum number of records to retrieve from each
