This is how it goes: 1. You create a dynamic field in the schema called "product_*". This means that while indexing, you can create fields starting with "product_" dynamically for a document. 2. If a document, doc1, is dealing with prod1 and prod2, you create fields called product_prod1 and product_prod2 and populate them with the corresponding "values". 3. If a patch for SOLR-247<https://issues.apache.org/jira/browse/SOLR-247>is committed, you can perform a facet query, as simple as: facet.field=product_*. This should give you results in the manner you expect. product_prod1:all values, product_prod2:all_values and so on ...
