[jira] [Created] (LUCENE-10467) Throws IllegalArgumentException for getAllDims(0)

Yuting Gan created LUCENE-10467:
-----------------------------------

             Summary: Throws IllegalArgumentException for getAllDims(0)
                 Key: LUCENE-10467
                 URL: https://issues.apache.org/jira/browse/LUCENE-10467
             Project: Lucene - Core
          Issue Type: Improvement
          Components: modules/facet
            Reporter: Yuting Gan


Currently, when calling getAllDims(0) in SortedSetDocValuesFacetCounts, it would throw a  NullPointerException. Other class that implements the getAllDims functionality could have the same issue, except for TaxonomyFacetCounts, which has been tested. 

It would provide better user experience by throwing an IllegalArgumentException when requesting topN = 0 for getAllDims.{{{}{}}}{{{}{}}}
