I'm creating this issue based on these comments [~abenedetti] made in
SOLR-17974...
{quote}Nested vectors -> build nested documents automatically (as this is the
route we've decided in Lucene after many discussions)
{quote}
...I haven't been following the lucene level discussions about supporting
multi-valued HNSW docs (or that a decision had been made that nested documents
was *the* solution) but I _DO_ have existing code that makes it easy to build
parent->(many)child docs where each child contains a single vector field value
(used for dealing with chunked vectors at my day job, which I was given
permission to share)
Attaching this for consideration.
The goal of this plugin (as i currently use it) is to make external clients as
agnostic as possible to the internal parent/child structures:
* External clients *ONLY* deal with indexing "parent" documents
* The internal plugins ensure that:
** One child documents is automatically created for each (individual) vector
in the "parent" document
** Any DBQs against parent documents automatically wrap all children of those
documents. (which we can do safely/automatically because our only use of
hierarchical documents are these vector based children; and clients should
never be sending us any DBQs _intentionally_ matching vector-child documents)
