This is the definition of the _version_ field in my index. I believe
this is how the field is defined in all Solr example configs:
<field name="_version_" type="long" indexed="false" stored="false"/>
The 'indexed="false"' in that definition means that querying on that
field is impossible. I suspect that it is not indexed in the sample
configs because querying is not needed for the field's function and not
indexing it makes the index a little bit smaller.
You would think that having stored as false would mean it wouldn't be
returned in search results ... but a field of that type has docValues
defined by default, and docValues functionality provides a value for
search results by default.
I do not know why you are running into a discrepancy on the _version_
field. It seems very odd.
