Yes, to me, the quoted phases above are synonymous.
But I believe we are also seeing a new type of index manifesting
itself, and this new index has yet to be named. Specifically, I'm
thinking of the index where various types of content is aggregated
into a single index and then queried. For example, instead of
providing a federated search against one or more library catalogs, a
Z39.50 accessible journal article index, a local cache of harvested
OAI content, etc., I think we are beginning to see all of these
content silos (and others) brought together into a single (Solr/
Lucene) index and searched simultaneously. I'm not sure, but I think
this is how Summon works.
