Another day, another Examine question ;)

I'm trying to display products with autocomplete. If I add this query to my URL: http://localhost:52242/json?searchTerm=epic it renderes out the products:

[{"id":"localhost:52242/mountain-bikes/specialized/epic-hardtails/epic-hardtail/","label":"Epic Hardtail","value":"Epic Hardtail"}

But I need to grap that searchTerm value on the run inside Autocomplete.

Master.cshtml

<form method="post" action="/soegning" name="searchTerm" autocomplete="on">
                    <input type="text" id="searchTerm" placeholder="Søg produkter" name="searchTerm" size="21" maxlength="120" autocomplete="on">
                        <input type="submit" value="">
                </form>

      $(function () {
        $("#searchTerm").autocomplete({
            source: "/json",
            minLength: 2,
            select: function (event, ui) {
                //Redirect user when item selected from the id in the JSON
                window.location.href = ui.item.id;
            }
        });
    });

json.cshtml

located in Views folder looks like this:

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage<ContentModels.Json>
@using ContentModels = Umbraco.Web.PublishedContentModels;
@using Examine;
@using Examine.SearchCriteria;
@using System.Web.Script.Serialization;
@{
    Layout = "Master.cshtml";
}

@{
    //Get the domain (http://localhost:6436)
    var siteURL =  Request.Url.Authority;

    //Get the values posted from the form
    var searchTerm = Request["searchTerm"];

    //Check if searchTerm is null from the posted form data...
    if (String.IsNullOrEmpty(searchTerm))
    {
        //Stop all other code running in this Macro
        <p>Nope</p>
        return;
    }

    var searcher = ExamineManager.Instance.SearchProviderCollection["ExternalSearcher"];
    var searchCriteria = searcher.CreateSearchCriteria(BooleanOperation.Or);
    var query = searchCriteria.GroupedOr(new string[] { "nodeName", "bodyText" }, searchTerm).Compile();
    var searchResults = searcher.Search(query);

    /*
    EXAMPLE JSON
    [{ "id": "http://localhost/about.aspx", "label": "About", "value": "About" }]
    */

    List<dynamic> searchResultKeyVals = new List<dynamic>();

    //Convert the search results as JSON
    foreach (var result in searchResults)
    {
        searchResultKeyVals.Add(new
        {
            id = siteURL + umbraco.library.NiceUrl(result.Id),
            label = result.Fields["nodeName"],
            value = result.Fields["nodeName"]
        });
    }

    JavaScriptSerializer serializer = new JavaScriptSerializer();
    var JSONResults = serializer.Serialize(searchResultKeyVals);
}

@* Ouput the JSON *@
@Html.Raw(JSONResults)
