Good News:
With the new maps API update it appears to now be possible to query by *name of ward* and name of stake.
I switched the query from Ward ID to Full Ward Name and that seems to be working:
Previous Behavior:
You could *technically* search by ward name before, but because the ranking algorithm was *really* bad, it often would return random results.
For example: a search for "Provo 192 YSA" would include other wards with "Provo" or "192" or "YSA" in the name or address, so things like "Canyon Ward" on "192 South" in Michigan might have shown up in the results and but it may or may not have returned the exact match.
Likewise, searching by ward id was only reliable in combination with some word from the name of the unit, otherwise it would match post office boxes and zip codes and such.
