Bug 515637

SUMMARY
I expect the search results for "st louis" to be a superset of the results for "st. louis", but all NOAA stations are missing from the former.

STEPS TO REPRODUCE
1. Open "Weather Report" widget settings, "Weather Station" tab
2. Type "st louis" in the search bar, note results
3. Replace search with "st. louis"

OBSERVED RESULT
"st louis" finds BBC stations but does not find NOAA stations.
Interestingly, two results are not a substring match: `Saint-Louis, Senegal, SN (BBC Weather)` and `Lambert-St. Louis International Airport, United States, US (BBC Weather)`

"st. louis" finds both BBC stations and NOAA stations

EXPECTED RESULT
Both queries find BBC stations and NOAA stations
