Subject: facet ID term map - take 1
X-Git-Url: http://lists.indexdata.dk/?a=commitdiff_plain;h=44cfe47e00cc8fba5097b16b1d62b1321b8c4268;p=pazpar2-moved-to-github.git

facet ID term map - take 1

In this scenario if pz:facetmap has a split: prefix, eg
 <set name="pz:facetmap:split:subject" value="facet_05"/>
Then the subjects will be split into a normal display facet
and an ID - separated by first colon. This makes it possible
to limit _one_ target's native facet IDs but will not work
for anything else - because these definitions are target specific!!
