If this time is more recent than the last time the indexer processed this URL, filter handlers (implementations of the IFilter interface) are called to extract the (possibly) changed data for that item. Returns the time that the URL was last modified. The IUrlAccessor interfaces provide access to important pieces of information through the methods described in the following table. The UrlAccessor object is instantiated and initialized by a SearchProtocol object. The IUrlAccessor4 interface extends the functionality of the IUrlAccessor3 interface with a method that identifies whether the content of the item should be indexed. The IUrlAccessor3 interface extends IUrlAccessor2 with a method that gets an array of user SIDs, enabling the search protocol host to impersonate these users to index the item.

The IUrlAccessor2 interface extends IUrlAccessor with methods that get a code page for the item's properties and its display URL, and that get the type of item in the URL (document or directory). It can also bind those properties to a protocol handler-specific filter (that is, a filter other than the one associated with the file name). Interfaceįor a specified URL, the IUrlAccessor interface provides access to the properties of the item that is exposed in the URL. The IUrlAccessor interfaces are described in the following table. IUrlAccessor, IUrlAccessor2, IUrlAccessor3, and IUrlAccessor4 The ISearchProtocol2 interface is an optional extension of ISearchProtocol, and includes an extra method to specify more information about the user and the item. The SearchProtocol interfaces initialize and manage your protocol handler UrlAccessor objects. Other than the three mandatory interfaces listed, the other interfaces are optional, and you are at liberty to implement whichever optional interfaces are most appropriate for the task at hand.

IFilter to filter proprietary files or to enumerate and filter hierarchically stored files.

IUrlAccessor to expose properties and identify appropriate filters for items in the Shell data source.

ISearchProtocol to manage UrlAccessor objects.

Implementing Protocol Handler InterfacesĬreating a protocol handler requires the implementation of the following three interfaces: We recommend this naming convention: companyName.scheme.įor more information on creating a Shell data source, see Implementing the Basic Folder Object Interfaces. Ensure that the protocol name that you select to identify your Shell data source does not conflict with current ones. Your protocol handler must be able to handle this URL syntax. As a result you cannot rely on the existence of a final slash to identify a directory versus an item.

The Windows Search Indexer trims the final slash from URLs. Represents a unique string that identifies the child item (for example, the file name). If no user security identifier (SID) is identified, the protocol handler is called in the security context of the system service.ĭefines the hierarchy of the store, where each forward slash ('/') is a separator between folder names. Identifies the user security context under which the protocol handler is called.

Identifies which protocol handler to invoke for the URL. The URL syntax is described in the following table. The URL that is the first node in the hierarchy is called the search root Windows Search will begin indexing at the search root, requesting that the protocol handler enumerate child links for each URL. Windows Search uses URLs to uniquely identify items in the hierarchy of your Shell data source.

The installation application can also add a search root and scope rules to define a default crawl scope for the Shell data source. Installing a protocol handler involves copying the DLL(s) to an appropriate location in the Program Files directory, and then registering the protocol handler through the registry.
