Hoss Man commented on SOLR-6024:
--------------------------------
Gah! .... I don't know what's up with my browser, because it just happened
again (firefox doesn't like tomas!)
bq. Yes, that was why I was adding the "-trunk" patches.
Yeah ... i think it makes sense to focus on adding test coverage to trunk (and
ferreting out any subtle bugs we've been missing due to the lack of test
coverate) and then worry about backporting the individual changes to 4x and
manually applying the neccessary StatsComponent.java change to conditionally
use UnInvertedField when needed.
bq. The "missing" stat won't work with this configuration (on trunk). It's
being calculated as:
isn't that a bug then? we should definitely be able to get "missing" info from
the DocValues API, and we should use it instead of depending on indexed=true
for a docValues field. right?

> It is east to re-produce with default example solr setup. Following types are
