    LUCENE-10085: Fix flaky testQueryMatchesCount (#538)
    
    Five times every 10 000 tests, we did not index any documents with i
    between 0 and 10 (inclusive), which caused the deleted tests to fail.
    
    With this commit, we make sure that we always index at least one
    document between 0 and 10.
