Extending CoreResultsWebPart - Setting defaults

Question

I'm in a process of extending CoreResultsWebPart - I'm trying to create something like "Who is Blogging" to show you most recent blogs from people. Following properties will be changed - so that when used it will be set as default.

1. XslLink (Done)
2. Location (to only Local Search Results)
3. Sorting

I'm unable to find how to setup Location. There is a property called Location which takes string. However I have tried with "LocalSearchResults" and I't doesn't work.

This is my code so far:

public class WhosBloggingWebPart : CoreResultsWebPart
    {
        protected override void OnInit(EventArgs e)
        {
            base.OnInit(e);

            base.UseLocationVisualization = false;
            base.XslLink = @"/Style%20Library/XSL%20Style%20Sheets/WhosBloggingModule/WhosBloggingXSLT.xslt";

            this.Location = "LocalSearchResults";
            this.FixedQuery = "contenttype:post AND NOT Title:\"Welcome to your Blog!\" AND url:\"*/site/*\"";
            this.QueryNumber = QueryId.Query2;

            this.DefaultSort = ResultsView.Modified_Date;
        }
    }

Answer 1

Set the location value to LocalSearchIndex

this.Location = "LocalSearchIndex";
