     if (!string.IsNullOrWhiteSpace(title))
     {
            var terms = title.Split(' ').ToList();
            items = items.Where(w => terms.Any(a => w.ItemName.Contains(a)));
     }

}

.OrderByDescending(p => p.CreatedAt)\r\n    .Where(p => p.Portal_Id == 1)\r\n    .Where(p => __terms_1\r\n      
.Any(a => p.ItemName.Contains(a)))' could not be translated.
