It seems like different search methods treat zero scoring docs a
little differently. Is this OK?
Some search methods on IndexSearcher check for score > 0.0f :
scorer.score(new HitCollector() {
public final void collect(int doc, float score) {
if (score > 0.0f && // ignore zeroed buckets
The search method that accepts a HitCollector doesn't check for a score of 0.
I wrote a test program and got a surprising result... instead of
getting a score of 0, I got a score of NaN. Now the NaN is passed to
the HitCollector, but excluded from the other search methods (since
NaN > 0.0f is false.... only NaN != 0.0f would be true). Is this
intended/OK?
Test Program Output:
Query=a:aaa^0.0
number of hits = 0
Found doc 0 with score NaN
Test Program: attached.
