LINQ查询显示如下结果

Question

我无法理解我在哪里出错，即使页面运行正常且没有错误，但查询仍然没有返回任何内容。这是代码：

    public void loadresults()
    {
        JobDescription objjobdes = new JobDescription();
        string search = Request.QueryString["result"].ToString();

        var jobquery1 = from objjob in db.Jobs
                        where objjob.JobTitle == search
                        select objjob.JobTitle;


        var eventquery1 = from objev in db.Events
                          where objev.Name == search
                          select objev.Name;


        var profilequery1 = from objprofile in db.Profiles
                            where objprofile.FirstName == search
                            select objprofile.FirstName;

        List<string> searchresult = new List<string>();
        if (jobquery1.Count() > 0)
        {
            lvsearchdetails.DataSource = jobquery1.ToList();
            lvsearchdetails.DataBind();
        }
        else if (eventquery1.Count() > 0)
        {
            lvsearchdetails.DataSource = eventquery1.ToList();
            lvsearchdetails.DataBind();
        }
        else if (profilequery1.Count() > 0)
        {
            lvsearchdetails.DataSource = profilequery1.ToList();
            lvsearchdetails.DataBind();
        }
        else
        {
            Response.Write("Your search did not match any results!");
        }
    }

在查询事物时，结果就是查询结果

  SELECT [Distinct1].[C1] AS [C1] FROM ( SELECT DISTINCT [UnionAll1].[JobTitle] AS [C1] FROM (SELECT [Extent1].[JobTitle] AS [JobTitle] FROM [dbo].[Jobs] AS [Extent1] WHERE ( CAST(CHARINDEX([Extent1].[JobTitle], @p__linq__0) AS int)) > 0 UNION ALL SELECT @p__linq__3 AS [C1] FROM [dbo].[Jobs] AS [Extent2] WHERE @p__linq__1 LIKE @p__linq__2 ESCAPE N'~') AS [UnionAll1] ) AS [Distinct1]

任何形式的帮助都会很好，同时也不要苛刻我是初学者。
