LUCENE-9991: Address bug in TestStringValueFacetCounts (#168) (#2504)
> Fix TestStringValueFacetCounts
> ------------------------------
>
> Key: LUCENE-9991
> URL: https://issues.apache.org/jira/browse/LUCENE-9991
> Project: Lucene - Core
> Issue Type: Bug
> Components: modules/facet
> Affects Versions: main (9.0)
> Reporter: Greg Miller
> Priority: Minor
> Fix For: main (9.0)
>
> Time Spent: 50m
> Remaining Estimate: 0h
>
> As reported by [~julietibs] in LUCENE-9950, there's a randomized test failure
> in {{TestStringValueFacetCounts}}. It's actually an issue with the test
> itself.
> Since count ties are broken in {{StringValueFacetCounts}} by ordinal, but the
> test doesn't know anything about the ordinals, the test breaks ties by the
> value itself before comparing results. The edge-case is if we only request a
> topN of 1, but the top result ties in count with other results. In this
> scenario, the result returned by the {{Facets}} might be one that sorts
> higher than another when secondarily sorted by value, but the test can't
> solve for this since it only sees the one result. Should be a fairly simple
> fix in the test case itself. Will do so shortly.
