I've been using SimpleGeo for doing some of my place data queries for a location-based app I'm building. They currently use Factual's data set. From what I can tell, there is no way to do partial text queries on place data, probably because of limitations on Factual's end.
The kind of query I mean is that "Starb" would return results for Starbucks in an auto-complete.
Testing out Google Places API yields the same results. Querying "Bullf" for Bullfrog Brewery near Williamsport, PA turns up nothing. Querying "Bullfrog" yields the correct result.
Do any geolocation/place APIs support this kind of partial keyword query?
