What is ElasticSearch need ?

What is ES?

It is essentially an internet search engine similar to google that is based on Lucene. It also functions as an analytics engine.It offers users with a distributed system.
It lets us store data, analyze, and search for large amounts of data rapidly and in real-time.
It is an engine that can search in full text. It is a full-text search engine. RDBMS or DBMS it isn’t possible to do a full-text search, but it is possible to do so in this.
It also provides a procedure to it’s log files and the message file by storing them inside the database.
The major distinction in elastich and RDBMS is that when we query RDBMS and it’s taking 10 seconds to produce the same result, elastic will be less than 10 milliseconds.
Elasticsearch has been developed by JAVA. It is an open-source software that is covered by the terms and conditions of the Apache License.

We already know, in RDBMS any query will take 10 seconds for each output, whereas for the same query Elasticsearch will be less than 10 milliseconds. This is why there is a great demand for elasticsearch.
For instance: If we search for anything on the E-Commerce website and it’s taking a long time to locate the item, it will result in a bad user experience and the customer will not ever want to return for the same search.
However, this issue can be solved making use of the elasticsearch.
It’s easy to put into place.
It can be useful in fuzzy searches (comeback with websites that are based on the search).
It can be useful in autocomplete. If we type something, it will autocomplete that particular word.
It can be useful in a quick search. It is very quick.
