	396	+=== Solr Search ===
	397	+
	398	+We added 3 new fields to the [[Solr Index>>design:Design.SolrSchema]] related to Nested Spaces:
	399	+
	400	+* spaces: the list of nested spaces, e.g. ['A', 'B', 'C']
	401	+* space_facet: used for [[hierarchical faceting>>https://wiki.apache.org/solr/HierarchicalFaceting]] (the 'facet.prefix'-based drill down approach)
	402	+* space_prefix: used to match descendant documents, e.g. all documents from space ##A.B## and all its descendants (like space ##A.B.C##)
	403	+
	404	+We also modified the value of the ##space## and ##space_exact## fields to contain the full local reference of the space (it was holding only the name of the last space prior to 7.2). Finally, the ##space## field has been deprecated in favour of the ##spaces## field.
