to query the search index. By default, results of this type of query are returned in
order of relevance rank, descending from most relevant to least relevant. Booleans
and wildcards are not currently supported out of the box with the default search
constructor Web Part by SharePoint Portal Server 2003. The Microsoft SQL Syntax for
Full-text Search (MSSQLFT) dialect can also be used to query the search index. Use an
MSSQLFT query with the SQL SELECT response format to specify different sort orders.
You will use the same set of controls for this sample application as you did for
the first one. However, they will all perform different functions. The text box will be the
string that you want to search for, the button will initiate the search, the tree view
will contain our search results including a hyperlink to the resource, and the list
view will just be used for providing feedback to the user.
As with the AreaService Web service, you need to provide credentials to the
search Web service. So, you will use the getUserCredentials function created earlier
in this chapter to help with this functionality.
Place the following code in the button1_Click function:
private void button1_Click(object sender, System.EventArgs e)
{
//1. Setup a variable containing the XML required for querying
// the Web service. Double quotes in the XML must be escaped
// with a backslash. The SEARCHSTRING will be replaced later with
// the actual string of keywords that the user wants
// to search for.

//2. Instantiate the proxy to the SearchWebService Web Service
SearchWebService.QueryService queryWS =
new SearchWebService.QueryService();
//3. Set credentials for authentication to the Web service
queryWS.Credentials = getUserCredentials();
