I have found that users of the system like to use index as the composite of all nodes/shards/slices that is searched in response to a query. It is the ultimate logical entity. Really, this is the same abstraction that users of Lucene have. They really don't want to care that a Lucene index is made up of several files and even possibly several indexes in various states of merging. The same should really be true of a parallel system, but more so.
