I have a data content witch contains complex data I just need index names which seem in Dynamic View in data. In debug mode I can see the datas but cant get them..
You can see the contents of data in image below):
if(hits.Count() > 0)
{
var data = hits.FirstOrDefault().Source;
var dataaa = JsonConvert.DeserializeObject(hits.FirstOrDefault().Source);
}

I found a solution with checking if selected index has documents; if yes,
I take the first document in index, and parse it to keys(field names) in client.
here is my func:
[HttpPost]
public ActionResult getIndexFields(string index_name)
{
var node = new Uri("http://localhost:9200");
var settings = new ConnectionSettings(
node,
defaultIndex: index_name
);
var esclient = new ElasticClient(settings);
var Documents = esclient.Search<dynamic>(s => s.Index(index_name).AllTypes().Source());
string fields = "";
if (Documents.Documents.Count() > 0)
{
fields = JsonConvert.SerializeObject(Documents.Documents.FirstOrDefault());
var data = Documents.Documents.FirstOrDefault().Source;
return Json(new
{
result = fields,
Success = true
});
}
return Json(new
{
result = "",
Success = false
});
}
and my js:
$.ajax({
url: "getIndexFields?index_name=" + $(this).val(),
type: "POST",
success: function (data) {
if (data.Success) {
var fields = JSON.parse(data.result);
var fields_arr = [];
$.each(fields, function (value, index) {
fields_arr.push(
{
id: value,
label: value
})
});
options.filters = fields_arr;
var lang = "en";//$(this).val();
var done = function () {
var rules = $b.queryBuilder('getRules');
if (!$.isEmptyObject(rules)) {
options.rules = rules;
}
options.lang_code = lang;
$b.queryBuilder('destroy');
$('#builder').queryBuilder(options);
};
debugger
if ($.fn.queryBuilder.regional[lang] === undefined) {
$.getScript('../dist/i18n/query-builder.' + lang + '.js', done);
}
else {
done();
}
}
else {
event.theme = 'ruby';
event.heading = '<i class=\'fa fa-warning\'></i> Process Failure';
event.message = 'User could not create.';
event.sticky = true;
$("#divfailed").empty();
$("#divfailed").hide();
$("#divfailed").append("<i class='fa fa-warning'></i> " + data.ErrorMessage);
$("#divfailed").show(500);
setTimeout(function () {
$("#divfailed").hide(500);
}, 3000);
}
},
error: function (a, b, c) {
debugger
event.theme = 'ruby';
event.heading = '<i class=\'fa fa-warning\'></i> Process Failure';
event.message = 'Object could not create.';
$("#divfailed").empty();
$("#divfailed").hide();
msg = c !== "" ? c : a.responseText;
$("#divfailed").append("<i class='fa fa-warning'></i> " + msg);
$("#divfailed").show(500);
setTimeout(function () {
$("#divfailed").hide(500);
}, 3000);
}
});
