- In this tutorial, Elasticsearch Tutorial for Beginners, Udemy instructor, Frank Kane will cover Elasticsearch, the Elastic Stack, Kibana, Beats, and Logstash in depth.
This free online tutorial has been updated for Elasticsearch 6! Elasticsearch is an important tool in your big data and data processing arsenal - often, it can return results in milliseconds when it would take Apache Spark or Hadoop hours!
Elasticsearch is not just for search, it is a full featured data analytics and visualization ecosystem that aggregate and analyze massive data sets very quickly.

We will start with a high level overview of the Elastic Stack ecosystem, and how its components (Elasticsearch, Beats, Logstash, and Kibana) all fit together, and how they are used.
Next we will cover how Elasticsearch organizes data, using documents, types, and indices.
Also covered:
• Inverted Indexes and the fundamentals of search engines
• TF/IDF (Term Frequency / Inverse Document Frequency)
• Elasticsearch APIs including REST, client APIs, and web-based UIs such as Kibana
• Sharding and how indices are hashed into shards
• Replication across primary and replica shards
You will learn what the Elastic Stack is all about, and how it achieves its high scalability and resiliency to failure at very low latencies. Understanding Elasticsearch architecture is the first step toward becoming a developer or administrator of an Elasticsearch cluster. You may find that an Elasticsearch cluster is a great complement to your Spark or Hadoop clusters, and it’s especially well suited for collecting and analyzing web log data.

This is the best video on elastic search on youtube, other tutorials don't show or explain the concepts but this explains the foundation with clarity
This is super clean and REALLY well explained. Thank you !
Informative, well-spoken, easy to understand.
This is the first time I feel like I understand how elasticsearch works. I was looking for good foundations, and I find them - very clear and great idea about the quiz !
Very clearly explained, I was a first timer on ES, understood it with one or two short rewinds. Liked the quiz with explanations!
Amazing! Professional! Clear and right on point.
Well done sir.
Liked your presentation.
Proper Introduction to all components of Elastic stack
and then moving into Elasticsearch made it easier to understand/visualize whole ecosystem.
Love it, Kane! Compact format AND lots of topics covered 👌
Had to come down here and appreciate your way to expaining. Super clean and the quiz at the end was fun as well. Thank you.
Frank has a very listenable voice.
This video gave me a total understanding on what elastic search means
The beginning is a bit confusing but to the end it all clears up great one !
Lucky to find this. Excellent tutorial.
Brilliantly and clearly explained!
Clear and concise, well explained.
Thanks! Extremely helpful!
Useful & Comprehensive...TY!
I like the quiz section at the end. it cements one's understanding
Wow, trying to understand elastic search and came across this video.. Well explained. +1 on the quiz at the end
Absolutely fucking incredibly well explained. OMG. Give this man a cookie!
i have a question, at 10:00 it talks about the inverted index and i get the idea, however i'm confused about the document it doesn't look like a JSON document which is the kind of documents that ElasticSearch works on, so is this just a simplified version of how things work ?
Oh my god. Are you the voice behind Webflow University? If not, it's seriously spooky how much you sound like him. :) Fantastic information. Thank you.
Great video.
Feedback: Very nice Video! Also, very nice presentation layout! To too loaded, not too sparse, the right balance between information and design!
I want to hear this guy explain everything. He is good!!!
Neat tutorial thanks.
So I can use ElasticSearch to work with my sql server?
Hi,
I have a question. Generally, for a document stored in the primary shard of a node, the copies of that document need to be stored only in the replicas of other nodes right? Because storing the copies in replicas of the same node doesn't make sense, because if the node goes down, the replicas are also lost.
You are correct. By default Elasticsearch will never allocate a replica to a node where there is already a copy (whether primary or replica) of that shard.
great thanks
finally understand index in elasticSearch!
Hi team
How we can subscribe for platinum features of kibana and how we can pay for that.
Top notch!
informative, can you add information how does elasticsearch store such that it allow fast aggregation ?
Neat! Very Helpful!
Nice concepts !
very well explained
Thanks a lot
Just great
OH MY GOD THIS WAS SO GOOD
Great content
Thanks!
Seems in a description you have provided a link to another course
Yes, I'd like the right link too :)
The lecture is very good 👍📌
I could answer all the quiz questions in the end, But I thing it would appropriate if you add to title of the tutorial that it's more suitable to architects or DevOps.
I like your voice man!
Thank you. But please may ask, of do my queries I elasticsearch, how to I get that data. If I want to train it for machine learning
Udemy intro is cool.
Shard total =( no of primary shard * no of replica ) + no of primary shard
👍😎
or easily: total_shards= no_of_primary_shards * (no_of_replicas + 1)
Can i get these slide ?
Good one
The link to the full course takes you to a machine learning with Python course instead.
Yes, I'd like the right link too :)
9:05 🖖
There's a typo (Elaticsearch) in both the title and the description.
Thank you so much for letting us know. We've updated the video. We appreciate the feedback.
@@udemy Gladly. Thanks for the helpful video!
18:50 there are things to "node" here
he wants to avoid a pop. He can control how much air bursts out when he says a p or t or k. Or he's Dutch.
what is lucene ?
Great introduction, to elastic search and the elastic stack, however i think that the word "introduction" should not be in the title
We're so glad you liked the video, thank you for your feedback. We really appreciate it.
16:37 is really confusing, I know by This INDEX has two PRIMARY SHARDs and two REPLICAs, it probably means this way
PUT /testindex
{
settings: {
number_of_shards: 2,
It's like when you're trying to calculate purchase price on an item (that isn't free), and your local economy levies a sales tax on that item:
t = tax rate (replicas)
u = price (primaries)
y = Purchase Price (primaries and replicas)
y = u + (u * t)
y = 5 + (5 * 3)
y = 20
Introduction or Overview, not Tutorial. :(
was not expecting this from Udemy
We're sorry you didn't enjoy the video, we appreciate your feedback and will review to make sure the video titles align with the content.
title is a bit misleading
wow
I'm a simple man: I see Star Trek, I press like.
Drop the playback speed to 0.75 and you'd think it's President Obama ! :) Excellent video BTW.
Close, but still very funny. Just needs to drop the voice about half an octave and it'd be spot on.
v clean video but I am worried whether this is still relevant in 2022?
galat link paste kar diye hain chachaa. Elasticseach bolkar Machine learning padhaa diye!

REST request for a web page?
GET request with a body?
What r u talkin bout?
that shit was confusing as fuck. It confuses me and i Know rest services, imagine someone who doesn't.
Thanks, but please someone who is looking for elasticsearch I think he know JSON, Restful ....
Did not like it. Does not adress the fundamental question, how do you go from your SQL/NoSQL/GraphDB to ElasticSearch. How do you sync data? Is it manual? Do you have connectors like Kafka? What is the lag/latency. What is the sync strategy? How it compares to full text search in traditional dbs? Sorry lots of kibana works and not much nutrients on the plate.
GET requests don't have a body...
that's not a tutorial
Not beginner-friendly
cannot understand his accent properly, or he is speaking inside his mouth, really hard time understanding him.
