Schema Class

Provides access to the property metadata management system for Enterprise Search.

System.Object
  Microsoft.Office.Server.Search.Administration.Schema

Namespace:  Microsoft.Office.Server.Search.Administration
Assembly:  Microsoft.Office.Server.Search (in Microsoft.Office.Server.Search.dll)
[SharePointPermissionAttribute(SecurityAction.LinkDemand, ObjectModel = true)]
public sealed class Schema

The Schema class is the entry point for managing the Enterprise Search metadata schema for a Shared Service Provider's search service. To use the Schema object, you must do the following:

  1. Add references to your application for the following dlls:

    • Microsoft.SharePoint.dll

    • Microsoft.Office.Server.dll

    • Microsoft.Office.Server.Search.dll

  2. Specify the Shared Service Provider for the search service using the SearchContext object. For more information about ways to retrieve the search context, see How to: Return the Search Context for the Search Service Provider.

The following topics contain code samples demonstrating how to use the Schema object model to perform various metadata management tasks programmatically:

How to: Retrieve the Managed Properties for a Shared Services Provider

How to: Create a Managed Property

How to: Delete a Managed Property

How to: Retrieve the Crawled Properties for a Category in the Search Schema

How to: Retrieve the Crawled Properties Mapped to a Managed Property

How to: Map a Crawled Property to a Managed Property

The following code example writes out the full list of managed properties to the console window. For a complete, step-by-step walkthrough of this sample code, see How to: Retrieve the Managed Properties for a Shared Services Provider.

Prerequisites

Ensure a Shared Service Provider is already created.
