Filter products with ElasticSearch concat a lot of filter

I've been trying to filter products with Elasticsearch for a few hours, unfortunately to no avail.
I need to find products that belong to certain categories and at the same time have selected several brands and one size.
Help :(

Parse() Can't Get All Element

i have smailler XML file i want to parse it .
<?xml version="1.0" encoding="utf-8"?>
<!-- GeeSuth Checker Time -->
<Geranal>
<AftrNoon Min="20" StartAftrNoon="05:00:00" EndAftrNoon="11:01:00" />
<Night Min="50" StartNight="2:00:00" EndNight="6:00:00" />
<AlFajr Min="100" StartAlfajr="9:00:00" EndAlfajr="10:00:00" />
</Geranal>
i want to get all the value in line , like
<AftrNoon Min="20" StartAftrNoon="05:00:00" EndAftrNoon="11:01:00" />
i need save the values in string paramater :.
Min
StartAftrNoon
EndAftrNoon
and save it in paramater ?
im using this :.
XmlReader ReaderXML = XmlReader.Create("Date.xml");
while (ReaderXML.Read())
{
ReaderXML.IsStartElement("Geranal");
if (ReaderXML.NodeType == XmlNodeType.Element && ReaderXML.Name == "AftrNoon")
{
//AftarNoon Fill
txt_Min_Aftrnoon.Text = ReaderXML.GetAttribute(0);
dt_Aftr_start.Text = ReaderXML.GetAttribute(1);
dt_aftar_End.Text = ReaderXML.GetAttribute(2);
}
if (ReaderXML.NodeType == XmlNodeType.Element && ReaderXML.Name == "Night")
{
txt_Min_Night.Text = ReaderXML.GetAttribute(0);
dt_Night_Start.Text = ReaderXML.GetAttribute(1);
dt_Night_end.Text = ReaderXML.GetAttribute(2);
}
if (ReaderXML.NodeType == XmlNodeType.Element && ReaderXML.Name == "AlFajr")
{
txt_Min_Fajr.Text = ReaderXML.GetAttribute(0);
dt_Fajr_Start.Text = ReaderXML.GetAttribute(1);
dt_fajar_end.Text = ReaderXML.GetAttribute(2);
}
}
It's Not get all elements value.

Just put all name/value pairs to a dictionary. Using Linq2Xml
var values = XDocument.Load(filename)
.Descendants("AftrNoon")
.First()
.Attributes()
.ToDictionary(a => a.Name, a => a.Value);
Now you can access them like
var min = values["Min"];
or
foreach(var kv in values)
{
Console.WriteLine(kv.Key + ":" + kv.Value);
}

To start with your XML has a small issue with the naming of the attributes that makes it hard to parse - the element AlFajr has a capital F, yet the attributes do not. If you can fix that then this code works nicely:
var xd = XDocument.Load("Date.xml");
var nodes =
(
from e in xd.Root.Elements()
let Min = e.Attribute("Min").Value
let Start = e.Attribute("Start" + e.Name.LocalName).Value
let End = e.Attribute("End" + e.Name.LocalName).Value
select new { e.Name, Min, Start, End, }
).ToDictionary(x => x.Name, x => new { x.Min, x.Start, x.End });
That gives me this:
Now I can use that to populate your fields very easily:
txt_Min_Aftrnoon.Text = nodes["AftrNoon"].Min;
dt_Aftr_start.Text = nodes["AftrNoon"].Start;
dt_aftar_End.Text = nodes["AftrNoon"].End;
txt_Min_Night.Text = nodes["Night"].Min;
dt_Night_Start.Text = nodes["Night"].Start;
dt_Night_end.Text = nodes["Night"].End;
txt_Min_Fajr.Text = nodes["AlFajr"].Min;
dt_Fajr_Start.Text = nodes["AlFajr"].Start;
dt_fajar_end.Text = nodes["AlFajr"].End;
Alternatively, you could also set up a dictionary for your text boxes and, using the above code, assign the values like this:
var textBoxes = new []
{
new { Name = "AftrNoon", Min = txt_Min_Aftrnoon, Start = dt_Aftr_start, End = dt_aftar_End },
new { Name = "Night", Min = txt_Min_Night, Start = dt_Night_Start, End = dt_Night_end },
new { Name = "AlFajr", Min = txt_Min_Fajr, Start = dt_Fajr_Start, End = dt_fajar_end },
};
foreach (var tb in textBoxes)
{
tb.Min.Text = nodes[tb.Name].Min;
tb.Start.Text = nodes[tb.Name].Start;
tb.End.Text = nodes[tb.Name].End;
}
Another alternative, that eliminates the need to fix the attribute naming issue, is to just do this:
var xd = XDocument.Load("Date.xml");
txt_Min_Aftrnoon.Text = xd.Root.Element("AftrNoon").Attribute("Min").Value;
dt_Aftr_start.Text = xd.Root.Element("AftrNoon").Attribute("StartAftrNoon").Value;
dt_aftar_End.Text = xd.Root.Element("AftrNoon").Attribute("EndAftrNoon").Value;
txt_Min_Night.Text = xd.Root.Element("Night").Attribute("Min").Value;
dt_Night_Start.Text = xd.Root.Element("Night").Attribute("StartNight").Value;
dt_Night_end.Text = xd.Root.Element("Night").Attribute("EndNight").Value;
txt_Min_Fajr.Text = xd.Root.Element("AlFajr").Attribute("Min").Value;
dt_Fajr_Start.Text = xd.Root.Element("AlFajr").Attribute("StartAlfajr").Value;
dt_fajar_end.Text = xd.Root.Element("AlFajr").Attribute("EndAlfajr").Value;

select only one random node from linq to xml

I have an XML file and I want to select only one random node. It seems like I'm almost there but the foreach with the var is looping. How do I select only one node and return it?
XML:
<human_check>
<qa>
<q>2 + 2</q>
<a>4</a>
</qa>
<qa>
<q>1 + 2</q>
<a>3</a>
</qa>
<qa>
<q>6 + 3</q>
<a>9</a>
</qa>
<qa>
<q>3 + 5</q>
<a>7</a>
</qa>
</human_check>
C#
public class human_check
{
public static string get_q()
{
try
{
string h = string.Empty;
Random rnd = new Random();
XDocument questions = XDocument.Load(#"C:\Users\PETERS\Desktop\human_check.xml");
var random_q = from q in questions.Descendants("qa")
select new
{
question = q.Descendants("q").OrderBy(r => rnd.Next()).First().Value
};
foreach (var rq in random_q)
{
h = rq.question.ToString();
}
return h;
}
catch (Exception ex)
{
throw ex;
}
}
}
Thanks in advance,
EP

Instead of setting up an ordering you could just pick a random element.
var qas = questions.Descendants("qa");
int qaCount = qas.Count();
h = qas.ElementAt(rnd.Next(0, qaCount - 1)).Element("q").Value;

var random_q = (from q in questions.Descendants("qa")
select q).OrderBy(r => rnd.Next()).First();
h = random_q.Descendants("q").SingleOrDefault().Value.ToString();

Static methods getting slower in when accesses by multiple threads

I have a situation where my C# application with .Net 4 is accessing a static method within a static class making the method perform slower than when accessed by a single thread. Say for example, If the method is called by a single thread it takes around 1.5 minutes to complete, whereas when called by 2 threads it takes 4 minutes to complete.
Any ideas/suggestion/best practices to increase the performance is highly appreciated. Thanks in advance for your responses.
Some more info:
This is an application which was using threadpool earlier to perform threading in some parts. I introduced parallel tasks. Hence it's a mix up of TPL and older Thread pool. Say for example one parallel task can have multiple threads. The machine has 24 CPU cores with 64GB RAM. I ran 2 processes which would have split to 5 threads each totalling upto 10 threads. During this the process got slower. I am pasting the code here for those who would like to inspect it and provide suggestions. Sorry for pasting long code. The code may not be having all current latest features as this was coded few years ago. Thanks once again.

There is nothing intrinsic about a static method that would make it slower when accessed by multiple threads, unless for example:
you have some shared resource that is being a throttle, such as a shared lock, or going to a single UI thread
you have more threads than available CPU cores, and it is simply having to do lots of switching
you are maxing out some other resource, such as disk IO, network IO, etc
Since you haven't posted any code, we can only guess.

finding a member property of an item in an array

I've passed in the whole sale object into this function. In that sale object, there are many childs e.g. saleOrderItem, Payment, User...
sale.payment is an array
Question:
1) How do I get the CodeNo from the `sale.payment' object? (as payment is an array)
2) How to get the sale.payment.CourseByTutor.TutorId (as payment is an array)
public static object GetSalesDataBySaleOrderID(SaleOrder sale)
{
return sale.saleOrderItem
.Where(s => s != null)
.Select(s => new {
Id = s.Id,
Username = sale.User.GetSingleUserById(s.UserId).Name,
Amount = s.Amount,
CodeNo = s.SaleOrder.payment.First().CodeNo,
TutorName = sale.User.GetSingleUserById(s.SaleOrder.payment.FirstOrDefault().CourseByTutor.TutorId).Name,
})
.ToList();
}
Here is how i bind the value to the object
private void SaveValueToObject()
{
saleOrder.UserId = UserInfo.Id;

}

I have a workaround and solved this question by adding the desired properties e.g. TutorId in the sale.saleOrderItem class. Thus making the direct access to the sale.SaleOrderItem.TutorId.
This sound stupid but it works.
