AdvancedSearch failure ... webservices.beta.netsuite.com/wsdl/v2008_2_0

when i am using the searchid from the previous search for advanced search it gives error search id not found.

Even the GetSavedSearch returns no records after a search is fired.

this is the code:
        ContactSearchAdvanced csa = new ContactSearchAdvanced();         
            ContactSearch cs = new ContactSearch();
            ContactSearchBasic csb = new ContactSearchBasic();           
            CreateSearchQuery("mar", csb, "FirstName");
            cs.basic = csb;
            csa.criteria = cs;
         
            SearchResult _searchResult = ServiceInstance.getInstance().search(csa);

//searchresult returns two records...

            GetSavedSearchRecord gsr = new GetSavedSearchRecord();
            gsr.searchType = SearchRecordType.contact;
            gsr.searchTypeSpecified = true;
            GetSavedSearchResult gssr = ServiceInstance.getInstance().getSavedSearch(gsr);
gssr returns no records...
           
            csa = new ContactSearchAdvanced();
