At present, these IDs can take one of two forms, depending on the
configuration of the Service Proxy being used: they may be based on
ZURLs, so a typical value would be something like:
+
pz:id=josiah.brown.edu:210/innopac|lui.indexdata.com:8080/solr4/select?fq=database:4902
+
Or they may be UDBs, so a typical value would be something like:
+
pz:id=brown|artstor
* `targetfilter` -- contains a CQL query which is used to find relevant
targets from the relvant library. For example,
+
udb==Google_Images
+
Or
+
categories=news
* `target` -- contains a single UDB, that of the sole target to be
used. For example
+
Google_Images
+
This is merely syntactic sugar for "targetfilter" with the query
- udb==NAME
+ `udb==NAME`
