Hello Islam

Using Find to provide autocomplete search results is certainly possible. The code below can be used to provide a suggested list of results for Name property of the Foo type:

public JsonResult Prefix(string term)
{
    var results = client.Search<Foo>()
        .Filter(x => x.Name.PrefixCaseInsensitive(term))
        .Select(x => x.Name)
        .StaticallyCacheFor(TimeSpan.FromHours(1))
        .GetResult();

    return Json(results.Select(x => x), JsonRequestBehavior.AllowGet);
}

Simply add the code above to a controller to use in your client side javascript.
