Pazpar2 features a cunning scheme by which you can associate various
kinds of attributes, or settings with search targets. This is done
search against a given target, or it can associate arbitrary name=value
pairs with groups of targets -- for instance, if you would like to
place all commercial full-text bases in one group for selection

+ Clients of the pazpar2 webservice interface can selectively override

+ can be used in conjunction with an external authentication system to
+ determine which resources are to be accessible to which users. Pazpar2
+ itself has no notion of end-users, and so can be used in conjunction
+ with any type of authentication system. Similarly, the authentication
+ tokens submitted to access-controlled search targets can similarly be
+ overriden, to allow use of pazpar2 in a consortial or multi-library
+ environment, where different end-users may need to be represented to
+ some search targets in different ways. This, again, can be managed
+ using an external database or other lookup mechanism.

contain one or more <set> elements. The settings and set

overrides those in the setting root element. Each set node must
specify (directly, or inherited from the parent node) at least a
target, name, and value.

many different settings, like search fields, retrieval syntaxes,
