Property Names

Note  Indexing Service is no longer supported as of Windows XP and is unavailable for use as of Windows 8. Instead, use Windows Search for client side search and Microsoft Search Server Express for server side search.

Each document property has a unique name determined by a COM-compatible naming scheme; that is, both a globally unique identifier (GUID) for a property set and a "_stg_propspec">PROPSPEC structure (which specifies a numeric ID or a string name) uniquely define each property. Each property optionally can have one or more friendly names, which act as aliases for the property. For example, the same property could have different friendly names in different languages.

The following table includes several examples of document property names.

These examples are just a few of the existing properties available in Indexing Service. For a complete list, see Filtering Well-Known Properties and List of Property Names for a Web Catalog. You can define and use additional properties for specific document types by entering the properties with the Microsoft Management Console (MMC) and by implementing a custom filter to extract them.
