Manage search scopes (FAST Search Server 2010 for SharePoint)
Applies to: FAST Search Server 2010
A search scope defines a subset of information in the search index. Scopes can for example direct a query to particular sites, or to items marked with particular property values.
Users can apply the search scope by selecting a pre-defined scope from a drop-down list in the search application, or they can specify the search scope directly in the Keyword Syntax query string by using the special property filter scope:scopename, where scope is a pre-defined property name and scopename is the name of the defined search scope.
In FAST Search Server 2010 for SharePoint, users can search two or more scopes by using
"AND" only. Linking scopes with
"AND NOT" is not supported. This is regardless of whether users search by using Keyword Syntax or if they use the Only the scope(s) option in Advanced Search. The search will only return results that are found in all selected scopes.
In FAST Search Server 2010 for SharePoint, a search scope is a pre-defined property filter expression that is specified in FAST Query Language (FQL) syntax. If you create the search scope by using the SharePoint graphical user interface, the FAST scope filter is auto-generated based on the rules created for the scope.
The number of items that are returned by the scope, will not be displayed in the View Scopes list. To see the number of items, you can run a query using the scope on the Search Center site, and then view the number of results in the result list.
If you need to specify more complex rules in the scope than what is available in the scope rule user interface, you can create or edit the scope by using Windows PowerShell. You specify the scope filter as a string according to the FQL query syntax. A scope filter can consist of any FQL syntax. For more information about FQL, see FAST Query Language (FQL) Syntax Reference.
A search scope is a query-time feature, and does not affect the index or index schema.
Scope matching does not include stemming and synonyms.
