Thanks @jbellis -- I'm not sure this change caused any difference.
Something in the past couple days tweaked the KNN results and this one jumped
out at me as a possibility.
This is the only detail the nightly benchmark produced:
```
Traceback (most recent call last):
File "/l/util.nightly/src/python/nightlyBench.py", line 1818, in <module>

File "/l/util.nightly/src/python/nightlyBench.py", line 701, in run
raise RuntimeError('search result differences: %s' % str(errors))
RuntimeError: search result differences:

'0.8285247') vs ([25459412], '0.8309758')"]
```
Unfortunately it is not so simple to reproduce these nightly benchmarks.
Note that they only check for exact hit/score differences and not any
precision/recall tradeoff.
