Managed Properties

The following managed properties are specific to FAST Search Server 2010 for SharePoint:

  • docvector   A similarity vector representation for this item. For more information, see Find Similar (FAST Search Server 2010 for SharePoint)

  • fcocount   The total number of hits for a given duplicate identifier in the original result set (before duplicate trimming). This value can be used to activate a "more hits from this site" link

  • fcoid   The numeric ID of the collapse field. It can be used to retrieve a specific hit from a collapsed group.

  • FileExtension   The file type extension of the matching item.

  • ServerRedirectedUrl   A URL used in association with Web Access Companion (WAC). This enables you to provide thumbnail previews in the result.

  • SpSiteUrl   The URL of the SharePoint site where the matching item is located.

  • Url   The URL of the matching item

Data Types

FAST Search Server 2010 for SharePoint does not support data type awareness in the returned query results. This means that all managed properties are returned with type String, even if they are numeric properties. Do not use the data type aware methods to retrieve properties in the query result if you intend to create a client that will be compatible with FAST Search Server 2010 for SharePoint and SharePoint Server search.

Hit Highlighted Summary

FAST Search Server 2010 for SharePoint can be configured to provide a hit highlighted summary for any managed property of type Text. In addition, the two reserved properties, HitHighlightedProperties and HitHighlightedSummary, are added to query results.

If you specify Result="Dynamic" in the index schema for the Body managed property (default setting), the hit highlighted summary is provided in the HitHighlightedSummary property. The same content is also provided in the returned Body managed property, but without the <c0> tags.

If you specify Result="Dynamic" in the index schema for any other managed property, the returned property will contain the corresponding hit highlighted summary. However, the <c0> tags are URL-encoded in the returned content.

Note

The Url managed property does not have Result="Dynamic" by default.
