Practical Elasticsearch Introduction for Immediate Use (Search Optimization Edition)

🤬 Why is Elasticsearch so hard to learn on your own?!

My name is Jaeseong Park . I started out as a developer without a major, worked as a CTO at several companies, and am currently working as an educator. There was a time when I also started as a developer without a major and studied Elasticsearch .

However, when I actually tried to learn Elasticsearch, it was difficult to find a lecture that was structured so that I could learn it quickly and easily and apply it to real life situations. As a result, I had a hard time learning by relying only on blog posts when I first started learning. Even the official documentation was complicated and difficult, so it was not easy to learn.

So, I created this course to teach you the basic syntax used in Elasticsearch and how to use frequently used functions. I will not only teach you how to use Elasticsearch, but also teach you the ability to apply Elasticsearch to various situations. If you learn this way, you will be able to apply it yourself after taking the course, and only if you can apply it yourself will you be able to apply Elasticsearch to your projects.

The goal of the lecture that I pursue is that after listening to the lecture, you, not me, can use Elasticsearch well in real life. If you listen to the lecture but don't understand what it says, don't know how to use it in real life, and don't remember anything, I think it's a poorly made lecture. If you learn something, you should be able to use it right away in real life.

Through this lecture, I hope that you will not only become someone who is well-versed in theories related to Elasticsearch, but also become a developer who can actually utilize Elasticsearch in personal projects or at work. Then, I will see you in the lecture.

✔ Note

The course is conducted on the assumption that you have a basic understanding of Spring Boot, Spring Data JPA, RDB (Mysql), and Docker . If you come across a part that you do not understand while studying, please use the Q&A bulletin board or 1:1 open chat room to ask questions right away . 😊

🚨 Be sure to check who is teaching you!

If you meet the wrong doctor, you may die at that moment because you cannot cure your illness. However, death ends with the pain of that moment. However, if you meet the wrong teacher and receive the wrong education, you will suffer throughout your life.

Due to wrong education, you may end up going to a company you don't want to work for, receiving a salary that is lower than you expected, and living a life of suffering because of it. Not only that, but because of the wrong education, your children will also inherit the wrong education.

I think that education can really change a person's life in a positive way, but on the other hand, it can also completely destroy a person's life. I think that's why education is such a heavy responsibility.

Therefore, please check who the person teaching you is, what kind of person they are, and what path they have taken, and then make a careful decision.

👋 Hello!
Now I introduce myself ( ⸝⸝•ᴗ•⸝⸝ )੭⁾⁾

hello!

I started studying development as a non-major . I have already been a developer for 6 years! Recently, I have been working as a developer while serving as CTO at two companies . Whenever I have free time, I have been giving coding lectures, consulting on company development, and giving lectures.

The number of students I have taught so far has already exceeded 24,000 (as of July 25th) ! I feel this every time I teach many students, but I cannot forget the sense of pride I feel in education, so I will continue to provide education at Inflearn.
(* Among the students, there are those who passed the exams at Kakao Pay, Yanolja, and Woowa Brothers)

Just as I have received a lot of help when I was going through hard times, I wanted to become someone who could help many other people. And I feel most proud and happy when the value I created through development has had a positive impact on others.

For these reasons , I hope that by sharing what I have worked hard to obtain, I can help those people live a slightly better life.

thank you!
