The Elastic website has a dedicated page to explain: https://www.elastic.co/what-is/elasticsearch
"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..."
I suggest understanding what it is first before comparing it to other databases.
A lot of databases handle many types of data.
Are you actually interested in learning about it or are you just criticizing the site?
Maybe try the Wikipedia article then: https://en.m.wikipedia.org/wiki/Elasticsearch
