Search for a string in my datasource dynamically


I am displaying an Rssfeed on my page by using XmlDataSource and Datalist controls.

I want the user to be able to limit the information that is returned to my datalist.  To do this I have a textbox on the form that allows the user to enter their search criteria.

I need to be able to dynamically create a query string utilizing the information that the user entered in the textbox.  I am also using a drop down list and allowing the user to select whether they want to search in the title, description, or all parts of the xml file.

I am having trouble figuring out how to reference the data contained in my textbox in my query string.  Where the query string says 'asp', I want to replace 'asp' with the content from my sSearch variable.  Can anyone tell me how to reference my variable in the query string???

string sSearch = txtSearch.Text;
        string SQuery = "";

        if (DropDownList2.SelectedIndex == 0)
            SQuery = "[contains(title), 'asp')]";
