James Dyer commented on SOLR-2491:
----------------------------------
I think this issue can go separately from SOLR-2564 and have it use ungrouped
queries. This little patch allows people to use both features in tandem now
rather than waiting for later (for instance, I have an app in production using
this patch now...) .
As a follow-up to SOLR-2564, it would be nice to give the user the option to
return # of grouped hits. If the end-user is receiving groups as results and
the app gives a message like "300 results (groups) returned", then in the case
of a misspelled query, any "did-you-mean" message that includes # of hits would
probably need to be consistent and give # groups rather than # documents. So
this would be useful additional functionality, whenever we indeed get grouping
that can return # groups...
Maybe a separate issue should be opened just for this, and it can be worked
after SOLR-2564 goes in?

> If specifying "spellcheck.maxCollationTries" and "group=true" on the same
> query, you never get any Spell Check Collations back. The problem is that
> SpellCheckCollator relies on ResponseBuilder.getToLog().get("hits") to see
> how many results each test query returns. When "group=true", the "toLog"
> isn't populated so SpellCheckCollator is unable to find a collation that can
> return results.
