Remarques

Crawled properties are the set of properties discovered by the Recherche de contenu d'entreprise index service component when crawling content. For more information about crawled properties, see Gestion des métadonnées.

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 Recherche de contenu d'entreprise 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.

Exemple

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 Procédure : récupérer les propriétés analysées mappées sur une propriété gérée.

Prerequisites

Ensure a Shared Service Provider is already created.
