Learn Elasticsearch from practical examples
You will be able to build a search engine soon
Elasticsearch is the most popular open-source enterprise search engine widely used in the industry. We have learned what it is and why it is so fast. We have also learned how to use Elasticsearch in Python. An index laptops-demo have been created and filled with some sample data on which the queries in this article will be based. If you haven’t read these two articles yet, it’s recommended to read them first. However, if you already have some knowledge about Elasticsearch, you can go ahead with this article with no problem.
In this article, we will use the Console of the Dev tools in Kibana to build the queries in Elasticsearch Domain Specific Language (DSL). Kibana is a free and open frontend application that sits on top of the Elastic Stack, providing search and data visualization capabilities for data indexed in Elasticsearch. Kibana also acts as the user interface for monitoring and managing an Elastic Stack cluster. It is very convenient to write Elasticsearch queries in Kibana because there are hints and autocompletion for indices, fields, and commands. The queries built-in Kibana can be used directly in other languages like Python. Therefore, it is always a good idea to write and test Elasticsearch queries in Kibana and then implement them in other languages.
