[This documentation is preliminary and is subject to change.]

The optional <property> element specifies the properties used by the location provider. These properties are specific to this location provider, so there is no predefined set of names to use. The <property> element has two attributes, as described in this topic.

Syntax

OpenSearchShortName: Short name of the search service
OpenSearchQueryTemplate: Template, formatted following the OpenSearch template convention, for the query service
MaximumResultCount: (number) Maximum number of results returned by the search service
LinkIsFilePath: (Boolean) If true, the provider tries to interpret returned items as files, using their extension to create the proper ShellItem in the view. If false, items are treated as URL shortcuts.
