Vigya Sharma commented on LUCENE-10649:
---------------------------------------
>From initial debugging, it seems that the test expects all {{maxDoc}}
>documents to be present in the docValues field, which is not the case. I
>printed {{leaf.maxDoc()}} and {{{}numbers.cost(){}}}, and they have different
>values:
{code:java}
System.out.println(" --> vigya - maxdoc: " + maxDoc + ", cost: " +
numbers.cost());
--> vigya - maxdoc: 351, cost: 103
{code}
It seems that for this random-test-path, we create a
{{SparseNumericDocValues(IndexedDisi disi)}} doc values producer, and the
IndexedDisi itself contains only 103 values. I wonder if something changed
recently, that breaks the assumption that NumericDocValues in this test will
always have all the docs indexed.
The IndexedDisi was also created with 103 values.
{code:java}
System.out.printf("\n--> creating IndexedDisi. numvalues: %d\n",
entry.numValues);
--> creating IndexedDisi. numvalues: 103
{code}
