Coinciding with the launch of the completion suggester, we've seen a very
large decrease in the zero results rate for prefix search
<http://discovery.wmflabs.org/metrics/#failure_breakdown>! In fact, the
zero results rate for prefix search is now lower than that for full text
search. Similarly, we've seen a decrease in the overall zero results rate
KPI <http://discovery.wmflabs.org/metrics/#kpi_zero_results>. Yay!
