Elasticsearch is developed in Java and open source with the Apache license. Hi Elasticsearch, I've been playing with the new cross_fields multi match type, and I've got to say that I love it. We have known some basic Elasticsearch Multi Match Queries. It offers a distributed, multitenant - capable full-text search engine with as HTTP (Hyper Text Transfer Protocol) web interface and Schema-free JSON (JavaScript Object Notation) documents.
