搜索请求无法连接到搜索服务

Question

我正在开发一个使用Sharepoint对象模型的SharePoint站点。我收到“搜索请求无法连接到搜索服务”消息，执行FullTextSqlQuery。 Office Sharepoint Server搜索和索引服务正在运行。我怎么解决这个问题？

这里是代码：

FullTextSqlQuery qry = new FullTextSqlQuery(SPContext.Current.Site); 
qry.QueryText = "SELECT Path, Title, Rank, Description FROM portal..scope() Where FREETEXT(*,'\"" + keys + "\"') ORDER BY \"Path\" DESC"; 
qry.EnableStemming = true; 
qry.ResultTypes = ResultType.RelevantResults; 
qry.KeywordInclusion = KeywordInclusion.AllKeywords; 
qry.AuthenticationType = QueryAuthenticationType.NtAuthenticatedQuery; 
ResultTableCollection queryResults = qry.Execute(); 
ResultTable queryResultsTable = queryResults[ResultType.RelevantResults]; 
DataTable queryDataTable = new DataTable(); 
queryDataTable.Load(queryResultsTable, LoadOption.OverwriteChanges); 
ResultTable queryResultsTable = queryResults[ResultType.RelevantResults]; 
DataTable queryDataTable = new DataTable(); 
queryDataTable.Load(queryResultsTable, LoadOption.OverwriteChanges);
