Re: How do I represent a group of customer key/value pairs
Thanks Lance. It looks like it's worth investigating. I've already started down the path of using a bean with @Field(map_*) on my HashMap setter. This defect tipped me off on this functionality: https://issues.apache.org/jira/browse/SOLR-1357 This technique provides me with a mechanism to store the HashMap data, but flattens the structure. I'll play with the ideas provided on http://wiki.apache.org/solr/HierarchicalFaceting;. If anyone has some sample code (java + schema.xml) they can point me too that does Hierarchical Faceting I would very much appreciate it.
