+# Use a custom security trimmer for SharePoint Server search results

 This how-to guides you through the steps to implement—create, deploy, and register—a custom security trimmer for Search in SharePoint by using Microsoft Visual Studio 2010.

 Search in SharePoint performs query-time security trimming of search results. However, there may be scenarios in which you want to perform custom security trimming. Search in SharePoint provides support for these scenarios through the  [Microsoft.Office.Server.Search.Query.ISecurityTrimmerPre](https://msdn.microsoft.com/library/Microsoft.Office.Server.Search.Query.ISecurityTrimmerPre.aspx) , [Microsoft.Office.Server.Search.Query.ISecurityTrimmerPost](https://msdn.microsoft.com/library/Microsoft.Office.Server.Search.Query.ISecurityTrimmerPost.aspx) , and [ISecurityTrimmer2](https://msdn.microsoft.com/library/Microsft.Office.Server.Search.Query.ISecurityTrimmer2.aspx) (deprecated) interfaces in the [Microsoft.Office.Server.Search.Query](https://msdn.microsoft.com/library/Microsoft.Office.Server.Search.Query.aspx) namespace.
