Sounds good to me.
With facets, you can help the user click on it and filter then the first
results (and digg into your documents). If you click on facets on my demo,
you will see this in action.
A common use case is the commerce web site. You should read this
wonderful post from Karel (aka Karmi)
Elasticsearch Platform — Find real-time answers at scale | Elastic
I learned everything about facets from this article.
For your data, it depends on what you want to show to your users.
That said, I think that Date Histogram will be useful for your Datetime
values, Term Facet for your Branch code, Range facet for Sell price.
I don't understand what are article numbers or if I understood well (it's
a unique number/id ?), I can't see a facet for it.
Does it help?

Ok! It's seem to be wonderful!
If I'm not boring you I want to understand the main architecture, I'm
going to build something like this :
- Asp.NET Frontend
- I build a request for ES and get the result (maybe using NEST and
not JSon directly)
- Bind the result to the user on table, charts and so on
It's a good way for ES or there are some "best practices" ?
With this type of data :
- Datetime
- Branch code
- Article number
- Sell price
How can Facets improve the user experience ?
I'm reading about that but I can't really understand what facets filter,
facets histogram and so on can help me in developing this.
Really, really thanks!

I would say: "it depends!" 
On my laptop, I built a demo with 1,3 m docs (more than 100 fields) with
5 facets (Terms, Range, Date histogram).
When computing on the full dataset, I get results in about 8-10 seconds.
When adding a query on top of it (and reduce my data set to 100k docs), I
get results in less than a second.
On a Laptop and with only 1,5 Gb allocated to the JVM ! It was just
amazing.
With a real server (64 Gb RAM with 32 Gb for ES), you will get really
better performance and you will be able to handle more documents
Yes, you can build your application from every langage as everything is
standard in Elasticsearch (REST API)...

I need to develop a web application that allow a user to search.
The application will start with 10TB of data must have a realtime
response.
The search engine will be so simple, at the beginning.
Imagine to have a document with these field :
- Data
- Branch code
- Article number
- Sell price
I have to give to a user a web page in which he can simply enter the value
and return all the matches document.
Do you think ES can handle this volume of data ? Millions of documents for
an initial size of 10TB.
I'm going to use .NET to develop the frontend because it's my favorite
platform (I'm evaluating to use bootstrap as your demo too).
What kind of query can better perform on ES in this scenario ?
Facets can be return together with the main query and applied in a second
time on the client ?
I've seen that your example is developed in Javascript, it could be
difficult to build something like that with a server-side technology like
Asp.NET ?
Thanks a lot!

Hi,
I'm new to ES and I'm start building a web application based on it.
I've read that Faces allows to filter the result of a query, but in a web
scenario after I bind the first result query to a control (let say a table)
if I want to filter it with the Facets I have to re-run my query ?
What is the common architecture use ?
I think it's not a good idea to store the result of the query in the user
session.
I just want to start with develping a simple web page to discover the
power of ES and understand how it can interact with a web application.
Thanks
