: I allways build solr index from scratch, so I don't have neither "pk" : attribute in "entity" tag (dataconfig.xml file) nor "UniqueKey" in index : schema. When I updated solr from 1.3 to 1.4 I got the following exception : during solr initialization:
This is in fact a bug in Solr 1.4... https://issues.apache.org/jira/browse/SOLR-1638 ... : Is "UniqueKey" in schema still optional in solr 1.4? Is "pk" attribute in : still optional in solr 1.4 DataImportHandler entities? As I can see in It is (suppose to be) optional. Some functionality requires is (QueryElevationComponent) but DataImportHandler is not (suppose to be) one of them. -Hoss
