CRUD operations using elasticsearch-py

Elasticsearch is written in Java but it is interoperable with non-JVM languages too. In this book, we will use its Python client, elasticsearch-py, as well as its Java client to perform all the operations. The best part of this Python client library is that it communicates over HTTP and gives you the freedom to write your settings, mappings, and queries using plain JSON objects, and allows them to pass into the body parameters of the requests. To read more about this client, you can visit this URL: http://elasticsearch-py.readthedocs.org/en/master/.

All the examples used in this book are based on Python 2.7. However, they are compatible with Python version 3 also.
