Specifies a SourceRequest object that returns the location of a local query, based on the query input. For example, a local query of the form "pizza new york" returns "pizza" in the Title field, "New York, NY" in the Description field, and the latitude and longitude of the geographic center of the city in the Location.Latitude and Location.Longitude fields, respectively, for eight markets.
A local query of the form "coffee 98052" returns "coffee" in the Title field, "98052" in the Description field, and the latitude and longitude of the geographic center of the ZIP Code in the Location.Latitude and Location.Longitude fields, respectively, for postal codes in US markets only.

Spelling

Specifies a SourceRequest object that returns spelling suggestions. A SourceRequest object of SourceType.Spelling returns one result per call (that is, per SearchRequest) in the Title field of the result. Although the mask ResultFieldMask.Title is the most efficient setting to use, SourceType.Spelling also returns the expected result, a string in the Title field, when set to ResultFieldMask.All.

The results of each SourceType specification are query-dependent. For example, SourceType.Spelling will only return a result if a spelling error is detected in the query string. QueryLocation responds to local queries of the form keyword, place name or keyword, ZIP Code only. PhoneBook results are returned for local queries and location-aware queries (queries for which a Location object is specified). InlineAnswers are returned only for the types subscribed to by users having an explicit contract with Microsoft. To experiment with different queries, and for an example that uses all supported SourceTypes, see the Comprehensive Windows Forms Application (C#) topic.
