Replace Delegate Control – SmallSearchInputBox

I've got a task to change the OOTB SharePoint search box control and I found this links is useful to customize it and prevent the search results keyword from "This site scope"

http://sharepointroot.com/2011/05/25/replace-sharepoint-delegate-control-smallsearchinputbox/

First step is to register the search box assembly to the master page files.

<%@ Register Tagprefix="SharePointWebControls" Namespace="Microsoft.SharePoint.Portal.WebControls" Assembly="Microsoft.Office.Server.Search, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

Then Replace SharePoint controls search box which is the syntax like this
SmallSearchInputBox" Version="4"/>

With this one

The search box property can be found on MSDN reference link here

Hope this helps,
