 // IMPORTANT CAVEAT: The tables below are NOT COMPLETE.  Developers
 // often forget to keep these tables in sync with the code when they
 // change scoring algorithms or add new providers.  For example,
 // neither the HistoryQuickProvider (which is a provider that appears
 // often) nor the ShortcutsProvider are listed here.  For the best
 // idea of how scoring works and what providers are affecting which
 // queries, play with chrome://omnibox/ for a while.  While the tables
 // below may have some utility, nothing compares with first-hand
 // investigation and experience.

When you're ready, please update the below tables with your provider and a rough
range.

I'll add comments now and can refine them later when we settle on a scoring
algo.
