How to use pagination - Spring Data Elasticsearch - Part 7

In this tutorial series we take a look at Elasticsearch and see how we can use it together with Spring Boot. To make things easier for use we use awesome Spring Data Elasticsearch. For all of those who are not familiar with it, Elasticsearch is a distributed, free and open search and analytics engine for all types of data, including textual, numerical, geospatial, structured, and unstructured. Elasticsearch is built on Apache Lucene and was first released in 2010 by Elasticsearch N.V. (now known as Elastic). Known for its simple REST APIs, distributed nature, speed, and scalability, Elasticsearch is the central component of the Elastic Stack, a set of free and open tools for data ingestion, enrichment, storage, analysis, and visualization. Commonly referred to as the ELK Stack (after Elasticsearch, Logstash, and Kibana), the Elastic Stack now includes a rich collection of lightweight shipping agents known as Beats for sending data to Elasticsearch.

In this video we take a look how we can use pagination with elasticsearch.

Boolean query:
A query that matches documents matching boolean combinations of other queries. The bool query maps to Lucene BooleanQuery. It is built using one or more boolean clauses, each clause with a typed occurrence. The occurrence types are:

I want to think you a lot for this videos, it is so important, you explain very well and you covered all what we could need when developing an application, thanks again

Thank you so much for creating this tutorial! It was really helpful in teaching me the usage of Elasticsearch.

To be 101% lacked the aggregations :)
But, really great videos!!!

[naylin]

thanks. I hope another lesson like aggregation in elasticsearch.

Great playlist! 💕
Can you please add a video on Scroll API and search after?
Thanks in advance 👋🏿

Looks like with case when "page" is set to 1 and "size" is set to 2, I get empty results. Because according to the logic "from" would be 2 and "size" is 2. But we should get 1 document

How about the Person class which was created with annotations?
What is handled automatically by spring boot and what is not when we do not manage the indices by ourselves?
Could you make a video about the same operations over Person class.

Also, another video with relational data could be also very useful.
Say we have a manttoone relation between 2 entitites.

And for the next stage, it could be handling both springdata jpa and elasticsearch together maybe?

excuse me sir I'm the new elasticsearch here Can we search the text by using percentage?

What is you have 1mil records? This will not work since from is max 10 000.
