Windows search 3026

A data store can be exposed to the Shell programming model as a container that uses a Shell data source. The items in a data store can be indexed by the Windows Search system using a protocol handler. For example, ISearchFolderItemFactory is a component that can create instances of the search folder data source, which is a sort of "virtual" data source provided by the Shell that can execute queries over other data sources in the Shell namespace and enumerate results.

It can do so either by using the indexer or by manually enumerating and inspecting items in the specified scopes. This interface permits you to set up the parameters of the search by using methods that create and modify search folders. If methods of this interface are not called, default values are used instead. Accessing the Windows Search capability indirectly through the Shell data model is preferred because it provides access to full Shell functionality at the level of the Shell data model.

For example, you can set the scope of a search to a library which is a feature available in Windows 7 and later to use the library folders as the scope of the query. Windows Search then aggregates the search results from those locations if they are in different indexes if the folders are on different computers. The Shell data layer also creates a more complete view of items' properties, synthesizing some property values. It also provides access to search features for data stores that are not indexed by Windows Search.

Doing so ensures a better user experience. Windows Search then collects and stores properties emitted by filter handlers or property handlers when an item such as a Word document is indexed.

This store is discarded and rebuilt when the index is rebuilt. Third-party developers can create applications that consume the data in the index through programmatic queries, and can extend the data in the index for custom file and item types to be indexed by Windows Search. If you want to show query results in Windows Explorer, you must implement a Shell data source before you can create a protocol handler to extend the index. However, if all queries are programmatic through OLE DB for example and interpreted by the application's code rather than the Shell, a Shell namespace is still preferred but not required.

A protocol handler is required for Windows to obtain information about file contents, such as items in databases or custom file types. While Windows Search can index the name and properties of the file, Windows has no information about the content of the file. As a result, such items cannot be indexed or exposed in the Windows Shell.

By implementing a custom protocol handler, you can expose these items. For a list of handlers identified by the developer scenario you are trying to achieve, see "Overview of Handlers" in Windows Search as a Development Platform. A Shell data source is sometimes known as a Shell namespace extension.

A handler is sometimes known as a Shell extension or a Shell extension handler. In Windows Vista and later, Windows Search is integrated into all Windows Explorer windows for instant access to search. Search related threads. Remove From My Forums. Asked by:. Archived Forums.
