Exclude Asset Library from search results by modifying search scopes

It’s possible to exclude SharePoint Lists from search results by excluding their types in the search scope definition.

Therefore you need to define an search scope rule based on a “property”. You have to use “contentclass” and a value. There are much lists of the possible values out in the web.

Value	Description
STS_Web	Site
STS_List	Custom List
STS_ListItem	Custom List item
STS_List_DocumentLibrary	Document Library
STS_ListItem_DocumentLibrary	Document Libary item
STS_List_Links	Link List
STS_ListItem_Links	Link List item
STS_List_Events	Event List
STS_ListItem_Events	Event List item
STS_List_Tasks	Task List
STS_ListItem_Tasks	Task List item
STS_List_Contacts	Contact List
STS_ListItem_Contacts	Contact List item
STS_List_Announcements	Announcements List
STS_ListItem_Announcements	Announcements List item
STS_List_DiscussionBoard	Discussion Board
STS_ListItem_DiscussionBoard	Discussion Board item
STS_List_GanttTasks	Gantt Task List
STS_ListItem_GanttTasks	Gantt Task item
STS_List_IssueTracking	Issue Tracking list
STS_ListItem_IssueTracking	Issue Tracking item
STS_List_Survey	Survey
STS_ListItem_Survey	Survey item
STS_List_PictureLibrary	Picture Library
STS_ListItem_PictureLibrary	Picture Library Item
STS_List_WebPageLibrary	Web Page Library
STS_ListItem_WebPageLibrary	Web Page Library Item
STS_List_XMLForm	(InfoPath) Form Library
STS_ListItem_XMLForm	(InfoPath) Form Library item
STS_List_850	Page Library
STS_ListItem_850	Page Library item
urn:content-class:SPSSearchQuery	Search Query
urn:content-class:SPSListing:News	News Listing
urn:content-class:SPSPeople	People
urn:content-classes:SPSCategory	Category
urn:content-classes:SPSListing	Listing
urn:content-classes:SPSPersonListing	Person Listing
urn:content-classes:SPSTextListing	Text Listing
urn:content-classes:SPSSiteListing	Site Listing
urn:content-classes:SPSSiteRegistry	Site Registry Listing

You can generally exclude list items from search by using the value “STS_ListItem_PictureLibrary” for the property “contentclass”.

But how to exclude items or lists of type “Asset Library” which is also a standard list template like “Document Library”, “Picture Library”, “Calendar List”, … and “Page Library” which has as code (850) as name. (Marked red in the list above.)

I checked the 14 hive and figured out the 850 is the list template ID of “Page Library”. And the list template ID of “Asset Library” is 851.

So I used the following query in the search box: “(scope:"All Websites") (contentclass:STS_List_851)”

I created a new search scope exclude rule on the site collection using “STS_List_851” in it worked! Now there are no more Asset Libary links in the search result. If you you “STS_ListItem_851” you can exclude Asset Library Litems.
