Hi Mike,
I fixed the test. The problem was as you noted because of the both-sides
exclusive range:
assertEquals("Returned count of range query must be equal to exclusive
range length", tTopDocs.totalHits, Math.max(upper-lower-1, 0) );
Your fix was not enough, because the test then would fail, if
upper==lower==9999, because 10000 cannot be found in index.
Sorry for two commits, my first fix was one Math.max() too much :)
