Whats' your current query? It's probably a question of building boolean
query by combining Solr queries.
Note, this datamodel might be a little bit overwhelming, So, if number of
distinct attributename values is around a thousand, just handle it via
dynamic field without nesting docs:
<field name="attributename_material ">brass</field>
<field name="attributename_material quality>plastic</field>
