Hi! I need to add the ability to search for content by the "Title" field among the 3 types (category, property, organization).

My controller:

public class SearchController : SurfaceController
{
    private readonly UmbracoHelper _uh = new UmbracoHelper(UmbracoContext.Current);

    [HttpPost]
    public ActionResult Find(string text)
    {
        var query = ExamineManager.Instance.CreateSearchCriteria()
               .NodeName("category").Or()
               .NodeName("property").Or()
               .NodeName("organization")
               .And().Field("title", text)
               .Compile();

        var result = _uh.Search(query);
        return PartialView("~/Views/Partials/FindResult.cshtml", result);
    }
}

The structure of my site:

-Categories

-----Category (has Title)

-Properties

-----Property (has Title)

-Organizations

-----Organization (has Title)

But it seems it does not work properly. Please any help
