Does LINQ to Entities not recognize the 'Boolean Like?

I'm having this error when trying to do one with query using LINQ to SQL after making the suggested changes:

{SELECT
'Extent1'.'idcliente', 
'Extent1'.'nome', 
'Extent1'.'pai', 
'Extent1'.'mae', 
'Extent1'.'informacao', 
'Extent1'.'datanascimento', 
'Extent1'.'foto'
FROM 'cliente' AS 'Extent1'
 WHERE (LOCATE(TRIM(@p__linq__0), 'Extent1'.'mae')) = 1}

C #

    [HttpPost]
    public ActionResult Index(string recebeNome, int recebeOpcao)
    {


        try
        {
            sistema_mobileEntities dao = new sistema_mobileEntities();
            IQueryable<cliente> sql;
            sql = null;

            if (recebeOpcao == 1)
            {

                //link to sql não tem like
                sql = from c in dao.cliente
                      where c.nome.StartsWith(recebeNome.Trim())
                      // where SqlMethods.Like(c.nome, recebeNome.Trim() + "%")
                      select c;

                TempData["opcao1"] = "nome";
            }

            if (recebeOpcao == 2)
            {
                sql = from c in dao.cliente
                      where c.pai.StartsWith(recebeNome.Trim())
                      select c;

                TempData["opcao2"] = "pai";
            }

            if (recebeOpcao == 3)
            {
                sql = from c in dao.cliente
                      where c.mae.StartsWith(recebeNome.Trim())
                      select c;

                TempData["opcao3"] = "mae";
            }

            return View(sql.ToList());
        }

        catch (Exception ex)
        {
            return Json("Erro ao consultar cliente" + ex.Message);
        }


    }
