Hi,

 I am trying to access the web service provided by sharepoint 2007 and use it in the ASP.NET application. I want to use the following Web Service.

 http://localhost/_vti_bin/search.asmx

http://localhost/_vti_bin/spsearch.asmx

And while executing the code, following error is being thrown.

Server was unable to process request. ---> Attempted to perform an unauthorized operation.

Following is the code I am using to access the Web Service.

 Please let me know, if you encounter similar errors.

Thanks

John

You should set the URL for the Queryservice object and set QueryService.PreAuthenticate=true

Please find the below code and change the queryService.Url if you'r conecting remote server.
Code:
        //The string containing the keyword to use in the search
        string keywordString = TextBox1.Text;
        //The XML string containing the query request information
        //for the Web service
        string qXMLString = "<QueryPacket xmlns='urn:Microsoft.Search.Query'>" +
        "<Query><SupportedFormats><Format revision='1'>" +
        "urn:Microsoft.Search.Response.Document:Document</Format>" +
        "</SupportedFormats><Context><QueryText language='en-US' type='STRING'>" +
        keywordString + "</QueryText></Context></Query></QueryPacket>";

        SPSearch.QueryService queryService = new SPSearch.QueryService();
        queryService.Credentials = System.Net.CredentialCache.DefaultCredentials;
        queryService.PreAuthenticate = true;
        queryService.Url = "http://localhost/_vti_bin/spsearch.asmx";
        System.Data.DataSet queryResults = queryService.QueryEx(qXMLString);
        GridView1.DataSource = queryResults.Tables[0];
        GridView1.DataBind();

 
Thanks&Regards,

Hi,

I got the webservice working.

But I'm having a very hard time to filter my search.

I want to for example get documents that belong to a certain document library and search on custom properties.

I can't figure out how to do it. I tried using the SQL query syntax but I only manage to retrieve the documents I want:

StringBuilder sb = new StringBuilder();

            sb.Append("<QueryPacket xmlns='urn:Microsoft.Search.Query'><Query>");
            sb.Append("<SupportedFormats><Format revision='1'>urn:Microsoft.Search.Response.Document:Document</Format>");
            sb.Append("<Format revision='1'>urn:Microsoft.Search.Response.Content:Content</Format>");
            //sb.Append("</SupportedFormats><Context><QueryText language='en-US' type='STRING'>new</QueryText></Context>");
            sb.Append("</SupportedFormats><Context><QueryText type='MSSQLFT' language='en-us'>select path,title,size,write,\"urn:schemas-microsoft-com:office:office#ows_ListTemplate\", \"DAV:iscollection\",IsDocument, displaytitle, description, \"DAV:getcontenttype\", rank from scope() where size > 0 and freetext('" + _searchQuery + "') and IsDocument like '1'-- </QueryText></Context>");
            sb.Append("<Range><StartAt>1</StartAt><Count>100</Count></Range>");
            sb.Append("<Properties></Properties><SortByProperties><SortByProperty name='IsDocument' direction='Ascending'/></SortByProperties>");
            sb.Append("</Query></QueryPacket>");



            SPSSearch.QueryService qWSSsearch = new SPSSearch.QueryService();
            qWSSsearch.Credentials = G4SCommon.GetCredentials();

This query works fine, but it returns to much information, I want to narrow the saerch to a certain document library and even to the contents of some custom fields.

If I trie to use these custom fileds I get an error. Has someone doen this before? Or does anyone has examples of complicated searches with WSS 3.0?

I got lots of code from SPS 2003, but it is not applicable anymore.
