Comentarios

Crawled properties are the set of properties discovered by the Enterprise Search index service component when crawling content. For more information about crawled properties, see Administración de metadatos.

Crawled properties are grouped by category, based on the protocol handler that is used. Use the GetAllCrawledProperties method of the Category class to get the collection of CrawledProperty objects representing the crawled properties for a specific category.

Crawled properties are mapped to managed properties to make them available for the Enterprise Search user experience. Use the GetMappedCrawledProperties method of the ManagedProperty class to get the collection of CrawledProperty objects that represent the crawled properties mapped to specific managed property.

Ejemplo

The following code example writes out a list of crawled properties, which are mapped to a specific managed property, to the console window. For a complete, step-by-step walkthrough of this sample code, see Procedimiento para recuperar las propiedades rastreadas asignadas a una propiedad administrada.

Prerequisites

Ensure a Shared Service Provider is already created.
