you're right, that was a mistake in my code - I did actually using cacheKey but
that didn't work so I was looking at the Java class for DIHCacheSupport to see
if there were any other settings I could use
https://lucene.apache.org/solr/5_4_0/solr-dataimporthandler/index.html?org/apache/solr/handl
Where did cachePrimaryKey comes from? The documentation has cacheKey :
https://cwiki.apache.org/confluence/display/solr/Uploading+Structured+Data+Store+Data+with+the+Data+Import+Handler
