Question

I’m trying to query the sharepoint search with the following code

    protected ResultTable Search(String query, SPWeb currentWeb)
    {
        ResultTable rt = null;

        try
        {
            FullTextSqlQuery q = GetFullTextSqlQuery(currentWeb);

            q.QueryText = query;

            q.RowLimit = int.MaxValue;
            rt = ((ResultTableCollection)q.Execute())[ResultType.RelevantResults];
            //q.Dispose();

        }
        catch (Exception ex)
        {
            rt = null;
            Logging.LogException(ex);
        }

        return rt;
    }

    /// <summary>
    /// Create base FullTextSqlQuery
    /// </summary>
    /// <returns>FullTextSqlQuery</returns>
    protected static FullTextSqlQuery GetFullTextSqlQuery(SPWeb currentWeb)
    {
        FullTextSqlQuery q = new FullTextSqlQuery(currentWeb.Site);

        q.Culture = new CultureInfo(1033);

        q.EnableStemming = false;
        q.TrimDuplicates = true;

        if (SPSecurity.AuthenticationMode != System.Web.Configuration.AuthenticationMode.Windows)
        {
            q.AuthenticationType = QueryAuthenticationType.PluggableAuthenticatedQuery;
        }
        else
        {
            q.AuthenticationType = QueryAuthenticationType.NtAuthenticatedQuery;
        }

        q.RowLimit = 200;

        q.StartRow = 0;
        q.IgnoreAllNoiseQuery = false;
        q.ResultTypes = ResultType.RelevantResults;

        return q;

    }

And no matter what i do i get this exception: Exception from HRESULT: 0x80040E01

I read suggestions i should reduce the rowlimit, but i get this exception even with a rowlimit as low as 20.

Answer 1

Putting the fulltextsqlquery in a using fixed the issue. Don’t ask me why.

                   using (FullTextSqlQuery q = GetFullTextSqlQuery(web))
                    {
                        q.QueryText = sqlQuery.ToString();
                        rt = ((ResultTableCollection)q.Execute())[ResultType.RelevantResults];
                        Logging.LogMessage(rt.RowCount.ToString());
                    }
