Chris M. Hostetter commented on SOLR-14595:
-------------------------------------------
Michael: I didn't directly test your change, but your reasoning and proposed
solution seem solid to me - i especially appreciate that you considered the
possibility of people explicitly setting overrequest on a {{prelim_sort = index
asc}} type situation.
In reading through the diff, i don't see any flaw with the substance of your
change, but have 2 minor nits...
* re: the situation with negative value that are not " == -1" ...
** i agree completely this is an oversight, and not intentional behavior ...
please don't document it
** instead let's just "fix" overrequest to behave consistently for all values
"< 0" (or throw an error if "< -1" if you'd prefer)
** I completely understand if you'd like to punt this to it's own Jira for
tracking/discussion purposes.
* re: {{testIndexAscRefineConsistency}} ..
** if "all" methods do in fact now now behave consistently, why did you change
the test to loop over more explicitly listed method names, instead of just
looping over {{EnumSet.allOf(FacetMethod.class)}} as suggested in the comment
you deleted?
** as things stand, you are redundently testing {{"stream"}}

> jenkins found a failing seed for TestCloudJSONFacetSKGEquiv that has nothing
> to do with SKG -- it shows that using {{method:enum}} can sometimes return
> different set of buckets then {{method:smart}} when computing a facet that
> uses {{"sort":"index asc", "refine":true}} _as a subfacet_ of some other
> facet.
> (In all the cases i've been able to trigger with more targetted testing, the
> "parent facet" needs to use a sort option that cause buckets to "sort worse"
> when more data is known about them -- ie: "count asc" or SKG -- but i haven't
> determined if that's actaully neccessary to trigger the fialure)
> original jenkins failure...
