LUCENE-10070: Skip deleted documents during facet counting for all documents
(#2584)
> "count all" faceting functionality counts deleted docs for multiple
> implementations
> -----------------------------------------------------------------------------------
>
> Key: LUCENE-10070
> URL: https://issues.apache.org/jira/browse/LUCENE-10070
> Project: Lucene - Core
> Issue Type: Bug
> Components: modules/facet
> Reporter: Greg Miller
> Priority: Minor
> Time Spent: 1.5h
> Remaining Estimate: 0h
>
> A few different {{Facets}} implementations supporting a "count all" style
> constructor that allows the user to not pass in a {{FacetsCollector}}
> instance. It advertises that it's equivalent to using a {{FacetsCollector}}
> populated with a {{MatchAllDocsQuery}}, but more efficient. It looks like,
> with the exception of {{FastTaxonomyFacetCounts}}, none of the
> implementations correctly account for deleted documents (have a look at
> {{FastTaxonomyFacetCounts}} for a correct example that consults "live docs."
> From what I can tell, the affected implementations are:
> * SortedSetDocValueFacetCounts
> * ConcurrentSortedSetDocValueFacetCounts
> * LongValueFacetCounts
> * StringValueFacetCounts
> I'll attach a PR shortly illustrating unit tests I wrote that confirm the bug.
