Using full-text containstable isabout in ASP.Net using VB.Net

Hi forum,

I have a doubt a SQL query, it works fine in the MS SQL Management Studio, but when I pass it to the code behind it does not work. This is the sql query in the SQL Management Studio that works:

select * from products, containstable(products, prod,'isabout("laptop acer" weight (1))') as resultado where products.ImageIDS = resultado.[Key] order by resultado.[Rank] desc

And this is the code behind with a query but it does not work:

    Private Sub BindGrid2()
        Dim use As SqlConnection

        use = New SqlConnection("Data Source=DESKTOP-50SIV8B\SQLEXPRESS;Initial Catalog=cupon2; User ID=sa_conmigo; password=Twanging_11CRM2020")
        use.Open()

        Dim queryy As String = "select * from products, containstable(products, prod,'isabout('" + searcht.Text + "' weight (1))') as resultado where products.ImageIDS = resultado.[Key] order by resultado.[Rank] desc"

        Dim DAA As SqlDataAdapter = New SqlDataAdapter(queryy, use)
        Dim DTT As New Data.DataTable

        searchid.Text = ""
        subc.Items.Clear()
        ids.Items.Clear()

        DAA.Fill(DTT)

        gv2.DataSource = DTT
        gv2.DataBind()

        use.Close()
    End Sub

The issue is that I do not know why it does not work and how is the correct construction into the VB.NET.

Thanks!!!
